Comparison of the presepsin levels between gram-negative and gram-positive bacteria. The presepsin levels after 4 h of incubation were significantly higher in gram-negative bacteria (median 273, [IQR, 218–352]) pg/mL) than in gram-positive bacteria (median 200, [IQR,143–275]) pg/mL, p = 0.0002, Wilcoxon rank sum test). The presepsin values in control group was 84.3(73.9–103) pg/mL and significantly lower than both gram-negative and gram-positive bacteria (p = 0.0002 and 0.0003, respectively, Wilcoxon rank sum test). IQR, interquartile range. The vertical line within the box represents the median sample value. The ends of the box represent the 3rd and 1st quartile, respectively. The whiskers denote maximal and minimal values (not including outliers)
