  1. Note: reference category for symptoms = having no symptoms or being not active/functioning; reference category for patients’ evaluation of their GP = being not satisfied with GP, having no trust in GP, and low appraised knowledge of GP
  2. aBlock B and C were analyzed without the conditional items concerning ‘incontinence aid’ and ‘sexual functioning’. Sub-analyses were performed for patients who completed the question regarding incontinence aid and the questions regarding sexual functioning. The effects of the variables in the sub-analyses were corresponding with the regular analyses (for some variables the significance changed slightly, but this was probably due to under power)
