  1. a N depends on percentage of registered values.
  2. b If at least one variable is a constant, a Kappa could not be calculated for all practices independently.
  3. c To determine Kappa (target values) for weight and height, BMI was computed.
  4. d Range: the minimal and maximal percentage or kappa per outcome.at practice level.
  5. * Significant difference between EMR and SRP based on McNemar test, p < 0.01
  6. # Not comparable due to different units of measurement
  7. - Not applicable
  8. SRP = Structured registration program, EMR = Electronic medical record, HbA1c = Glycosylated haemoglobin
