Based on the mean Ngb value, patients in this study were classified into two groups: those having Ngb ≥ 8.0 ng/ml were included in the high Ngb group, and those having Ngb < 8.0 ng/ml were included in the low Ngb group. Mean Ngb value is the average of Ngb day 1, day 2, day 3, day 5, and day 7 values的平均值. Values are n (%), mean ± SD, and median (25%–75%).
