Parameter estimates for paternal age categories from sensitivity analyses excluding individuals diagnosed with mental illness.

Paternal age <20 20–24 25–29 30–34 35–39 40–44 45–49 50–54 55–59 >59
Ever committing a violent crime Regression estimate 0.27* 0.16* 0.01 Ref. 0.06* 0.12* 0.14* 0.21* 0.31* 0.59*
Number of violent crimes Regression estimate 0.08* 0.02 −0.01 Ref. 0.02* 0.09* 0.02 −0.18* 0.18* 0.21*

Note: Estimates for individuals without any diagnosis of schizophrenia or bipolar disorder. GLM-analyses for the two different outcomes adjusted for covariates (treating maternal age as categorical). Offset variable is modeled as 1 + q*(time at risk). The estimates for “Ever committing a violent crime” are changes, per unit in offset, for the regression on probability for committing at least one crime using the complementary log-log link. The estimates for “Number of violent crimes” are changes in the regression on the intensity, per unit in offset, of criminal offenses using the log link.
