¹Adjusted odds ratio (OR) for the highest life skill category, or standardized regression coefficient β for continuously distributed outcomes. Results for continuously distributed variables are shown with 3 decimal points, and OR with 2 points. All analyses are adjusted for age, sex, ethnicity (except for analyses of White participants), father’s education, own education, and cognitive function.

²P is for linear gradients across life skill categories.
