^aLinear regression analyses were performed separately for each of the five KIDSCREEN subscales as the dependent variables.

^bThe independent variables were grouped into seven blocks: B1–B7.

ͨThe strength of the associations is described in terms of standardized regression coefficients and adjusted R².

ͩThe variable was recoded into three categories: “0–4 days” (none, 1–4 days), “5–10 days” (5–7 days, 8–10 days), or “ > 10 days”.
