a MENA: Middle Easterners/North Africans. Multilevel linear regression models with random effects at general practice level were used to estimate the ethnic differences with Westerners as reference adjusted for individual characteristics (age, gender, diabetes duration and education), general practitioner characteristics (gender, specialist status and years working as general practitioner in Norway) and county of residence in Norway. * No overlap in 95% CIs, indicating significant difference between Westerners and the particular minority group. The number of observations included in univariate/multivariate analyses for mean HbA1c were 9059/8300, respectively. The corresponding number of observations included in regression analyses for mean BP were 8897/8178 and for LDL-cholesterol 6866/6313
