WebbFor a rare outcome, a proportion-mediated measure can be obtained from the direct and indirect effect odds ratios by the formula OR DE (OR IE −1)/(OR DE OR IE −1). If there is no exposure-mediator interaction (i.e., if θ 3 = 0), these expressions simply reduce to exp( θ 1 ) for the direct effect and exp( β 1 θ 2 ) for the indirect effect. http://davidakenny.net/cm/mediate.htm quality q factorWebb12 feb. 2012 · So, for example, an odds ratio of 0.75 means that in one group the outcome is 25% less likely.
