1 Mean sum score of categories I to III reflecting the consultation

2 During the voucher programme some doctors were visited more than once by SPs, but for this analysis only the first visits were considered. After the intervention 1 SP was seen by a Nurse.

3 Outcome of the Mann Whitney test (comparing the mean sum score of men and women) only p-values ≤ 0.10 are reflected.

4 Outcomes of the Kruskall Wallis test, only p-values ≤ 0.10 are reflected.

5 For each clinic the mean score is considered. Column 'before ' is based on 17 observations, column 'during' on 30 observations and column 'after' on 18 observations, only p-values ≤ 0.10 are reflected.
