Linear regression analysis comprises the study of the association between two variables, and analysis are based on fundamental assumptions: (Choose false assumption) The independent variable is not random. The value of the residual (error) is zero. The value of the residual (error) is constant across all observations The value of the residual (error) is different across all observations. The residual (error) values follow the normal distribution. 6. Regression analysis includes several variations: (choose incorrect answer) Non-parametric model Simple linear model Nonlinear model 7. The Evidence-based healthcare (EBHC) approach can be broken down into five steps: (Choose false step) Define a research question Search for the independent variable randomly Critically appraise the evidence for its validity and usefulness Implement useful findings in clinical practice Evaluate the practice of what you have decided to do when appropriate. 8. Non-parametric methods should be used whenever: The observations do not approximately follow a normal distribution The dependent variable is random The value of the residual (error) is not correlated across all observations 9. In statistical analyses, when comparing categorical variables instead of numerical variables, scientists use: t-Test ANOVA Chi-Squared 10.

Two most typical examples of prospective research in medicine are: Case-control studies and Observational studies Cohort studies and Experimental studies Cross-sectional studies and Qualitative studies 27. Using a national US database, rates of lung cancer were determined among New Yorkers, Texans and Californians. Lung cancer prevalence was 25% in New York, 30% in Texas and 20% in California. The researchers concluded that living in Texas is associated with higher rates of lung cancer. Type of study is: Case-control study Retrospective cohort study Experimental study Cross-sectional study Prospective cohort study 28. Using a national US database, rates of lung cancer were determined among New Yorkers, Texans and Californians. Lung cancer prevalence was 25% in New York, 30% in Texas and 20% in California. The researchers concluded that living in Texas is associated with higher rates of lung cancer. What can be determined? Odds Ratio Prevalence of disease Relative risk Regression coefficient 29. A group of 100 New Yorkers who smoke were identified based on a screening questionnaire at a local hospital. These patients were compared with another group that reported no smoking. Both groups received follow-up surveys asking about the development of lung cancer annually for the next 3 years. The prevalence of lung cancer was 25% among smokers and 5% among non-smokers. Type of study is: Case-control study Retrospective cohort study Experimental study Cross-sectional study Prospective cohort study 30. A group of 100 New Yorkers who smoke were identified based on a screening questionnaire at a local hospital. These patients compared with to another group that reported no smoking.

Sensitivity is: The validity relevant to identifying those who are ill The validity relevant to identifying those who are healthy The validity relevant to identifying those who are exposed The validity relevant to identifying those who are non-exposed 33. Information bias may arise or occur: When there is a strong association between the variable that is measured and a confounding factor that either is not measured or is measured with a large random error Due to a flaw in study design, when groups to be compared have been selected in different ways In retrospective studies in which the issues under study are known to both the observer and the observed In prospective studies in which the issues under study are known to the observer 34. The selection bias may occur or arise: In retrospective studies in which the issues under study are known to both the observer and the observed When there is a strong association between the variable that is measured and a confounding factor that either is not measured or is measured with a large random error Due to a flaw in study design, when groups to be compared have been selected in different ways In prospective studies in which the issues under study are known to the observer 35. The statistical confounding may occur or arise: In retrospective studies in which the issues under study are known to both the observer and the observed Due to a flaw in study design, when groups to be compared have been selected in different ways When there is a strong association between the variable that is measured and a confounding factor that either is not measured or is measured with a large random error In prospective studies in which the issues under study are known to the observer 36. Bias is traditionally classified as (incorrect answer) The selection bias The information bias The exposure bias The statistical confounding 37. Attributable risk for the population (PAR) is calculated: RR/(RR – 1) Re /(Re – R0) p(RR – 1)/(1+ p(RR – 1)) p(Re – R0)/(1+ (RR – 1)) 38.

If all persons with deficiencies in pancreatic insulin production have symptoms of type I diabetes, and these persons are from the general population (i.e., they were not included in the study sample because of other deficiencies that could cause these symptoms), one can conclude that all persons with deficiencies in pancreatic insulin production have symptoms of type I diabetes. The explanation is according to: Deduction (deducting modes of inference) Induction (inducting modes of inference) Abduction (abducting modes of inference) Coherence (coherence modes of inference) 71. If all persons with type I (insulin-dependent) diabetes are known to have deficiencies in pancreatic insulin production (rule), and Mr. D has type I diabetes (case), then Mr. D has deficiencies in pancreatic insulin production (conclusion). The explanation is according to: Deduction (deducting modes of inference) Induction (inducting modes of inference) Abduction (abducting modes of inference) Temporality 72. The pragmatic theory of truth argues: It is circular when truth depends on what works, and researchers’ assessment of what works depends on their conception of what is true Something is true if it corresponds to some truth maker things in the world A scientific hypothesis or theory is true if it coheres with other hypotheses or theories. If it is completely out of the realm of established knowledge, it is most likely untrue 73. The correspondence theory of truth argues: It is circular when truth depends on what works, and researchers’ assessment of what works depends on their conception of what is true Something is true if it corresponds to some truth maker things in the world A scientific hypothesis or theory is true if it coheres with other hypotheses or theories. If it is completely out of the realm of established knowledge, it is most likely untrue 74. The coherence theory of truth argues: It is circular when truth depends on what works, and researchers’ assessment of what works depends on their conception of what is true Something is true if it corresponds to some truthmaker things in the world A scientific hypothesis or theory is true if it coheres with other hypotheses or theories. If it is completely out of the realm of established knowledge, it is most likely untrue 75.

Three areas in which researchers and institutional review boards should apply ethical principles: (one is incorrect) They maintain high commercial standard The informed consent process The assessment of risk and benefit The selection of human subjects 93. The Belmont Report identifies three basic ethical principles, that should guide researchers in making the best ethical judgments in human subject research. These three principles are: Treat patients equally, respect person confidentiality, justice Respect for persons, beneficence, justice Treat patients equally, beneficence, be selfless in treating patients Respect for persons, treat patients equally, beneficence 94. – 95. Which one of four principles of the Nuremberg’s code provided to you is formulated incorrectly? The voluntary consent of the human subjects is absolutely essential The experiment shouldn’t be such as to yield fruitful results for the good of society, unprocurable by other methods or means of study, and random and unnecessary in nature The experiment should be so designed and based on the results of animal experimentation and knowledge of the natural history of the disease or other problem under study that the anticipated results will justify the performance of the experiment No experiment should be conducted where there is a prior reason to believe that death or disabling injury will occur; except in those experiments where the experimental physicians also serve as subjects. 96. Methodology filters contain general search strategies and may consist of complex search strategies: (choose one incorrect answer) Used to elicit quantity rather than quality Methodology filters are adapted to the structures of individual databases Devised and tested to retrieve high-quality research papers Devised and tested to retrieve high-quality research papers 97.

Points to Keep in Mind When Choosing a Research Problem (choose incorrect answer) Select biological problems that apply to organisms, organs, or cells in vivo. Don’t stay away from research questions that have emerged primarily from in vitro studies, unless those questions clearly apply to in vivo situations as well. Think strategically— divide challenging research projects into smaller steps without losing sight of the final goals. Do not be so afraid of having ideas “stolen” that it prevents a productive exchange of ideas and collaborations 136. Do not be so afraid of having ideas “stolen” that it prevents a productive exchange of ideas and collaborations Don’t select biological problems that apply to organisms, organs, or cells in vivo. Stay away from research questions that have emerged primarily from in vitro studies, unless those questions clearly apply to in vivo situations as well. Do not be afraid of choosing a big, challenging research problem Think strategically—break big research problems into a series of smaller steps, but stay focused on the long-term goals. 137. – 138. – 139.
