LOS and Steps multivariate models adjusted for age and frailty only

All other multivariable models adjusted for age, gender, frailty, fear of falling, physical performance on admission and the baseline score

Abbreviations and possible score ranges: LOS: length of stay (nights); Steps: average daily step-count; SPPB Score: Short Physical Performance Battery [a higher score reflects a better physical performance, range 0–12]; IND: ability to walk independently on level surfaces; VAS SR Health (EQ 5D5L): Visual Analogue Scale EuroQol 5-Domain 5-Level, [range 1–100]; READMISSION: medical readmissions
