Note. aOR: adjusted odds ratio; cat.: categorical; CI: confidence interval; con.: continuous; SE: standard error.

^a Respondents with age of last treatment lower than the minimum age of onset across the six mental disorders and suicidal outcomes under study are coded as not having received treatment.

^b To obtain pooled estimates of prevalence, each country was given an equal sum of weights.

^c Bivariate models adjust for socio‐demographic (gender, age, parental educational level, parental marital status, place raised, religion, sexual orientation, and current living situation), college‐related predictors (expected to work on a student job, academic performance in high school, and most important reason to go to university), and country membership.

^d Multivariate models adjust for socio‐demographic (gender, age, parental educational level, parental marital status, place raised, religion, sexual orientation, and current living situation), college‐related predictors (expected to work on a student job, academic performance in high school, and most important reason to go to university), country membership, and for predictors shown in the rows.

^e F‐test to evaluate joint significance of six types of mental disorders. ddf: denominator degrees of freedom; Ndf: numerator degrees of freedom.

^f F‐test to evaluate joint significance of categorical predictor levels. ddf: denominator degrees of freedom; Ndf: numerator degrees of freedom.
