Note: GTPS Greater trochanteric pain syndrome; Where cell values were less than 5 Fisher Exact tests was used. *Statistically significant (p < 0.05).
CSI Corticosteroid injection - numbers carried forwards.
^a Baseline and 12-month data does not include those excluded from 11-year follow-up, but does include those lost to follow-up
