Abstract

Contrary to the position taken by Lewis (1989), several articles have demonstrated an association between season of birth and the risk of schizophrenia after controlling for the age-incidence effect. The method used by Pulver et al. (1983) was misinterpreted by Lewis. Clarification of this method is provided along with additional references related to the season-of-birth issue.
