TL;DR
It is concluded that PA and PP are closely related and can be interconverted with moderate accuracy and produce similar effect sizes when odds ratio and relative risk are used as effect sizes.
Abstract
We conclude that PA and PP are closely related and can be interconverted with moderate accuracy. They also produce similar effect sizes when odds ratio and relative risk are used as effect sizes. When absolute difference in percent abstinent is used as an effect size, PA produces a smaller effect size than PP. We believe trials should continue to report both PA and PP outcomes to enhance comparisons across studies.
