  1. The table shows means ± standard deviations for parametric data and medians [interquartile range] for nonparametric data. Differences in the numeric data between groups were analysed by regression with a bootstrap analysis; *: p-value < 0.05 vs group 5. #: p-value < 0.05 vs group 4. Differences in the proportion of patients with PIMs were analysed by pairwise two-sample z-tests among groups 3, 4, and 5; Ɨ: p-value < 0.001 vs group 5. Abbreviations: SBP systolic blood pressure, PS peripheral saturation, TP temperature, FRIDS Fall-risk-increasing medications, PIMs Potentially inappropriate medications. Number of persons with missing data for each variable: age: 0, body mass index: 24 (0, 1, 6, 6, and 11 in group 1, 2, 3, 4, and 5, respectively), SBP at admission: 2 (2 in group 5), lowest blood pressure during admission: 8 (1, 2, and 5 in group 3, 4, and 5, respectively), PS: 4 (4 in group 5), TP: 8 (2 and 6 in group 3 and 5, respectively), estimated glomerular filtration rate: 1 (1 in group 4), sodium; 2 (1 in group 4 and 5), number of drugs, FRIDs and PIMs: 0
