  • Note: Unless otherwise indicated, the statistics used are Fisher exact. The analysis of the precipitating events and duration of symptoms is limited to the symptomatic groups.

  • ANOVA, analysis of variance; ASC, asymptomatic controls; GTPS, greater trochanteric pain syndrome; OA, osteoarthritis.

  • *ASC versus GTPS: p=0.928; ASC versus: p=0.049; GTPS versus OA: p=0.057.

  • †ASC versus GTPS: p=0.019; ASC versus OA: p=0.650; GTPS versus OA: p=0.134.
