Association between age and FIM scores in males (A–D) and females (E–H).

Notes: FIM scores were measured at both hospital admission and discharge. FIM gain was calculated as the change in FIM score at hospital discharge. Length of hospital stay was counted as the total number of days spent in the hospital. The Spearman’s rank correlation test was used for statistical analysis and P-values of <0.05 were considered statistically significant. FIM score at admission: panel (A) and (E); FIM score at discharge: panel (B) and (F); FIM gain: panel (C) and (G); length of hospital stay: panel (D) and (H).

Abbreviations: FIM, Functional Independence Measure; yr, years; NS, not significant.
