*Better guideline adherence, ≥5 procedures vs poor, < 5 measures done (9 indicators: HbA1c measurement >2 times a year; blood pressure measuring , ECG examination, serum creatinine, endocrinologist consultation, eye fundus examination, leg examination for pulse and neuropathy, LDL, BMI – at least one time a year).
**data from separate logistic regressions.
***only significant variables were included into final model
