Statistical analysis:
For our population characterization, continuous variables were presented
as mean ± standard deviation (SD), and categorical variables were
presented as frequency and percentages. In a univariable analysis we
compared demographic, clinical and hospitalization characteristics
between every two groups; surgical treatment (yes\no),
admission duration (more and less than 20 days) and glucose levels (mean
glucose ≥ 140, mean glucose ≤ 140). Parametric variables were compared
using t-tests and categorical variables were compared with Chi-square or
Fisher exact tests. Variables found to be nonparametric were compared
using Mann-Whitney test.All p-values were based on a two-tailed test of
significance, with a p-value<0.05 considered as significant.
All statistical analyses were conducted using SPSS Version 25 (SPSS
