PUNAFCC: Stata module to compute population attributable fractions for case-control and survival studies

punafcc calculates confidence intervals for population attributable and unattributable fractions in case-control or survival studies. punafcc can be used after an estimation command whose parameters are interpreted as log rate ratios, such as logit or logistic for case-control data, or stcox for survival data. It estimates the log of the mean rate ratio, in cases or deaths, between 2 scenarios, a baseline scenario ("Scenario 0") and a fantasy scenario ("Scenario 1"), in which one or more exposure variables are assumed to be set to particular values (typically zero), and any other predictor variables in the model are assumed to remain the same. This ratio is known as the population unattributable fraction (PUF), and is subtracted from 1 to derive the population attributable fraction (PAF), defined as the proportion of the cases or deaths attributable to living in Scenario 0 instead of Scenario 1.
