*Based on logistic regression analysis correcting for age (stratification variable, cut-off 50 years).
†Based on logistic mixed model analysis correcting for age (stratification variable, cut-off 50 years) and variation at the level of the GP practice, patient and repeated observations. The level-3 variance (GP practice) was equal to 0. The interaction between group and time was not significant.
