^aThe HOOS JR is scored from 0 to 100, where 0 represents total hip disability and 100 represents perfect hip health.

^bAUROC between 0.7 and 0.8 is considered acceptable, and between 0.8 and 0.9 is considered excellent.

^cA score of 50 represents the mean of the general population, and higher scores indicate better physical or mental health. AUROC = area under the receiver operating curve; PROMIS = Patient-Reported Outcome Measurement Information System; PCS = physical component score; MCS = mental component score.
