Effect of preoperative ESM mass on hospital stay
Excluding 33 in-hospital mortalities, we analyzed the correlation
between preoperative ESM mass and the duration of hospital stay in 86
patients. Overall, the ESM index presented a weak but significant
negative linear correlation with the duration of hospital stay, whereas
the HU of the ESM did not indicate a significant correlation (ESM index;
r = -0.21, p < 0.05, HU of the ESM, p < 0.33)
(Figure 2 ).
