  • a A test was defined as positive if followed by reimbursement of antibiotics (ACT code J01) within a week of the performed test.

  • b Urinary stix is used as a part of the diagnosis of urinary tract infections. CI = confidence interval. IRR = adjusted incidence rate ratio. Adjusted IRRs aggregated by age 0–6 years; adjusted for parity (indicator capped at 4); sex of child, gestational age (three groups); maternal age at birth; age of child; calendar year; maternal income (three groups); education level (three groups); cohabitation (four groups); paternal depression (four groups), paternal and maternal mental comorbidities (dichotomous). The reference group for the adjusted IRRs was children of mothers with no depression.
