  1. Incident OA: Any OA at follow-up in a hip with Croft < 3 at baseline
  2. Model 1: unadjusted; Model 2: age and sex adjusted; Model 3: adjusted for sex, age, weight and height, adolescent activity level and HBM status
  3. Odds in hips with cam morphology compared to hips without cam morphology
