Study Notes
Study Design
- A prospective study design starts with the exposure and follows participants forward in time to observe the development of outcomes.
Prospective vs. Retrospective Studies
- The main difference between prospective and retrospective studies is the direction of inquiry: prospective studies move forward in time, while retrospective studies look backward in time.
Bias in Prospective Studies
- Selection bias is less prone in prospective studies because participants are selected based on their exposure status and then followed over time.
Temporal Sequence
- The temporal sequence in prospective studies refers to the chronological order in which events occur, ensuring that the cause precedes the effect.
Strength of Prospective Studies
- The strength of prospective studies lies in their ability to establish causal relationships between exposures and outcomes, as they allow researchers to observe the development of outcomes over time.
