  • SF-MPQ, Short-Form McGill Pain Questionnaire; NA, data not applicable; SHIM, Sexual Health Inventory for Men; PHQ-9, Patient Health Questionnaire-9.

  • a Includes all patients enrolled into observation period.

  • b Denotes comparison of feedback arm with the management arm; Poisson regression used to compare number of observations.

  • c First assessment denotes symptom score from first month of observation period.

  • d Based on number of male patients: n=163 for overall study population, n=65 for feedback arm, n=55 for nurse management arm.
