Fig. 4: IRR and IRD of suicide attempt among mothers compared with the corresponding week among fathers: a nationwide register-based study in Sweden, 2001–2021.
From: Sex difference in parental risk of suicide attempt during and after pregnancy in Sweden
The analyses are based on aggregated data from 2,196,276 pregnancies (1,236,816 mothers and 1,175,674 fathers). The follow-up during pregnancy was censored at week 40 due to few subsequent cases. The dots represent the actual IRRs and IRDs, and the error bars represent their 95% CI. P values are two-sided and adjusted for multiple comparison (Supplementary Table 5). The dashed lines represent results when using restricted cubic spline with 4 knots, placed at 5th percentile, 35th percentile, 65th percentile and 95th percentile of distribution of weeks on the relevant x axes. The shaded areas indicate 95% CI of the smoothed results. The IRRs and IRDs were adjusted for country of birth, age, calendar year, education level, civil status, category of income, primiparity, history of psychiatric disorders, history of suicide attempt and season, all derived at the start of each period.
