Much controversy exists regarding proper methods for the selection of variables in confounder control.

This paper presents the results of a Monte Carlo simulation of several confounder selection criteria, including change-in-estimate and collapsibility test criteria.

In situations in which the best decision (of whether or not to adjust) is not always obvious, the change-in-estimate criterion tends to be superior, though significance testing methods can perform acceptably If their significance levels are set much higher than conventional levels (to values of 0.20 or more).
