Logistic models present the individual odds ratio in the setting of multivariate testing for final variables included in each LT-FS model. The c-statistic and Akaiki Information Criteria (AIC) are presented for each multivariate LT-FS model and, for comparison, frailty by SPPB (score ≤9) and FFP (score ≥3).
