  1. Note: The following sub-domain scores were computed - GH general health, PF physical functioning, RP role physical, VT vitality, SF social functioning, RE role emotional, MH mental health
  2. The following summary scores were computed - PCS, Physical Component Summary; MCS, Mental Component Summary
  3. Note: GH01, BP08, MH09, and VT10 are SF-12v2 items where higher scores indicate poorer health status; all other items are scored such that higher scores indicate better health status
  4. **Correlation is significant at the 0.01 level
  5. *Correlation is significant at the 0.05 level
