Table 1 A summary of the simulation results

From: Testing for Sufficient-Cause Interactions in Case-Control Studies of Non-Rare Diseases

 

Proposed method

Risk-scale RERI test

Odds-scale RERI test

Odds-scale PRISM test

Type I error rate

Stable at 0.05 for all scenarios.

Extremely small, very conservative test.

Small at low disease prevalence values, but inflated when the disease prevalence is greater than 0.4.

Stable at 0.05 at low disease prevalence, but inflated even at low disease prevalence values with larger sample sizes.

Power

Reached more than 80% in all scenarios.

Much less powered compared with the proposed method

Much less powered compared with the proposed method

Comparable to (when the disease prevalence is 0.02) and greater than (when the disease prevalence is greater than 0.2) those of the proposed method.
