  3. The first hospital visit concerning an STI diagnosis during the unexposed follow-up and the first hospital visit concerning an STI diagnosis during the exposed follow-up were both counted in all analyses
  4. CI confidence interval, HBV hepatitis B virus, HIV human immunodeficiency virus, IRR incidence rate ratio, N number
  5. IRR was adjusted for attained age (10–12, 13–15, 16–18, 19–21, 22–25, 26–29, 30–34, 35–39, and 40–44), calendar years (5-year group), and parental education levels (low/missing, medium, and high) as a proxy for socioeconomic status
