Temporal associations with child ADHD
As shown in Figure 1, the period-specific hazards indicate that at pre-
and early school-age, the ADHD risk was lower among ever SSRI/SNRI
exposed compared with non-medicated (wHR: 0.31, 95% CI: 0.13-0.76). In
the age band 7-9 years, this risk was elevated among the exposed
relative to both non-medicated (wHR: 1.93, 95% CI: 1.22-3.05) and
discontinuers (wHR: 2.59, 95% CI: 0.94-7.12). Within this age band, the
ADHD hazard was greater with SSRI/SNRI exposure for longer duration.
