Estimated means and standard errors (bar) across follow-ups for patients with and without type 2 diabetes at baseline. Only subscales with a significant interaction effect of type 2 diabetes and follow-up are illustrated. The somatization, depression, anxiety, and General Severity Index (GSI) subscales of the “Symptoms Checklist” (SCL-90) are scored from 1 to 4 with higher scores indicating more mental distress. The physical function and physical role subscales of the “Short Form Health Survey 36” (SF-36) are scored from 1 to 100 with higher scores reflecting better health-related quality of life.
