  1. a n total population = 623 for calculation of mean GFI score because 15 of the patients in whom it could be determined with certainty whether they had a GFI score ≥ 4 had missing values for some GFI questions. b Differences were evaluated with the Independent Samples t-test. c Differences were evaluated with the Pearson Chi-Square test. FI, Frailty index.
