Ratios are expressed with respect to references categories for SI (no SI) and pain symptoms (no pain in the respective location); models on pain variables include missings (no response); Model 1: unadjusted, only adjusted for 116 clusters (schools); Model 2: adjusted for sociodemographic variables: gender, age, school type, and living situation at home; Model 3: further adjustment for all sub-scales of the YSR except for somatic complaints.
