  1. aBecause P of follow-up and P of project × follow-up were both >0.05, the analysis was repeated without the terms project and project × follow-up included in the model. The P value is that of the latter analysis.
  2. bIn the analysis, HbA1c was logarithmically transformed. The results have been transformed back to the original scale.
  3. c P <0.00128 (to preserve a family-wise error rate of less than 0.05, the significance level was adjusted to 0.00128 using Holm’s test).
  4. HbA1c: Glycated Haemoglobin.
  5. PAID: Problems Areas In Diabetes.
  6. HCCQ: Health Care Climate Questionnaire.
  7. PCD: Perceived Competence in Diabetes Scale.
  8. TSRQ: Treatment Self-Regulation Questionnaire.
