Notes: *Statistic significance comparing to no-risk (GNRI>98) group; the categorical data was compared with Pearson chi-square tests; the normally distributed and non-normally distributed continuous data were analyzed by Unpaired Student’s t- and Post-Hoc Mann–Whitney U-tests, respectively. Significant values are indicated in Italic.
