We tested the ability of the QPAR to discriminate between individuals with impaired physical functionality (mPPT), falls risk (TUG) and the presence of frailty (CHSA rating). Panel A: The QPAR demonstrated good discrimination between normal and impaired physical functionality as determined by mPPT scores with an AUC 0.747 (95%CI: 0.69–0.79, p < .001). Panel B: The QPAR showed good discrimination between low and increased falls risk determined by TUG times with an AUC 0.730 (95% CI: 0.67–0.79, p < .001). Panel C: The QPAR demonstrated good discrimination between individuals with and without frailty by CHSA staging with an AUC 0.769 (95% CI: 0.72–0.82, p < .001).
