Multilevel regression analysis.

*Adjusted for patient characteristics (sex and age).

†Adjusted as model I+organisation characteristics (the percentage of temporary employees and the mean rate of sickness absence days in the HC).

‡Adjusted as model II+HC service area characteristics (educational level of the residents, median income and unemployment rate).

HbA1c, glycated haemoglobin; HC, health centre.
