Reference category: 11–12 months after exposure.
Cohort 1: Adjusted for age, calendar period, parity status, previous history of induced abortion and family history of psychiatric disorders. Parity status, induced abortion history and family history of psychiatric disorders: time-dependent variables.
Cohort 2: Probability of psychiatric contacts 12 months after a pregnancy resulting in fetal death:
<6 weeks: 1.24% (95% CI 0.94 to 1.55), N=64 cases;
6–12 weeks: 0.78% (95% CI 0.71 to 0.84), N=532 cases;
13–19 weeks: 0.75% (95% CI 0.55 to 0.97), N=51 cases;
20 weeks+: 1.95% (95% CI 1.50 to 2.39), N=72 cases.
Controls/reference population: 0.63% (95% CI 0.60 to 0.66).Thirty-one of the 776 cases had missing information on gestational age, and 26 had late entry and were excluded from the analyses.
