What is the conclusion regarding the presence of multiplicative effect modification based on visual inspection of the stratum-specific estimates of the relative risk?
What is the conclusion regarding the presence of multiplicative effect modification based on visual inspection of the stratum-specific estimates of the relative risk?
- The presence of multiplicative effect modification is not relevant in this context.
- There is no evidence of multiplicative effect modification as the relative risks are consistent across strata.
- The conclusion cannot be determined based on the given data.
- There is evidence of multiplicative effect modification as the relative risks vary across strata. (correct)
How can you confirm the conclusion regarding multiplicative effect modification?
How can you confirm the conclusion regarding multiplicative effect modification?
- By calculating the odds ratio for each stratum.
- By comparing the total number of LBW and NBW infants.
- By conducting a separate randomized trial for each stratum.
- By calculating the Mantel-Haenszel estimate of the relative risk. (correct)

- No, there is no evidence of effect modification on the additive scale.
- Effect modification is not relevant in assessing respiratory disease risk.
- The data provided is insufficient to determine effect modification on the additive scale.
