Data are given as incidence rate ratio (95% confidence interval).

^aAdjusted for age, calendar period, birth complications (number of diagnoses related to childbirth), reproductive history, somatic co-morbidities (Charlson co-morbidity index) and family history of psychiatric disorders. If a woman had records of more than one of the diagnoses of interest (dual diagnoses), she contributed with information in more than one category.
