Table 3. BMI and sepsis outcomes.

Variable	Low BMI group (<18.5 kg/m2) (n = 103)	Normal BMI group (18.5≤ BMI <25.0 kg/m2) (n = 314)	High BMI group (≥25.0 kg/m2) (n = 131)	p-value
28-day mortality, n (%)	22† (21.4)	35 (11.2)	19 (14.5)	0.032
In-hospital mortality, n (%)	25 (24.3)	51 (16.2)	28 (21.4)	0.142
ICU-free days, median (IQR)	18 (4–24)	22 (12–25)	20 (5–24)	0.066

Abbreviations: BMI, body mass index; ICU, intensive care unit; IQR, interquartile range.

†: vs. normal BMI group.

†: p-values <0.016 for multiple comparisons (after Bonferroni correction) were considered statistically significant.
