Abstract
In this issue, Zammit et al explore how five dichotomised risk factors work together to predict risk for non-affective psychosis in a large Swedish cohort. In this editorial, we review these findings, and comment on both the nature of additive v. multiplicative models and the meaning of statistical interactions.
