  1. a Estimates were adjusted for age, gender (male = 0, female = 1), cricket seasons played, playing status (current = 0, former = 1), history of joint injury (no joints injured = 0, sustained a joint injury = 1), and history of orthopaedic surgery (never had an orthopaedic surgery = 0, underwent orthopaedic surgery = 1)
  2. b SF-8: Short-Form 8 Health Survey; Physical Component Scores (PCS) were calculated using norm based scoring (population norm 50 SD 10, high scorer = better health-related quality of life); Mental Component Scores (MCS) were calculated using norm based scoring (population norm 50 SD 10, high scorer = better health-related quality of life)
