Highest values in each category are marked in bold.

CI: confidence interval; LR+: positive likelihood ratio; LR−: negative likelihood ratio; mHHS: modified Harris Hip Score; iHOT-12: 12-item international Hip Outcome Tool; MCID: minimal clinical important difference; SCB: substantial clinical benefit; PASS: patient acceptable symptom state.
