  1. Appropriate = prescribing antibiotics when reference test is positive and not prescribing antibiotics when reference test is negative
  2. Ovrertreatment = prescribing antibiotics when reference test is negative
  3. Undertreatment = not prescribing antibiotics when reference test is positive
  4. Permutation LR test to assess whether treatment decision at the day of the index consultationa or at the day of the final treatment decisionb differs between groups: a) no culture, b) culture performed in practice, c) culture performed at hospital. Hierarchical model with practices as a random intercept and adjusted for: complicated versus uncomplicated UTI, offensive smell, anamnesis score, microscope and culture in practice availability
  5. cWhen not performing culture, first treatment decision is the final treatment decision
