Antibiotics for fever in patients without perforation after gastric endoscopic submucosal dissection and endoscopic submucosal excavation may be unnecessary: a propensity score-matching analysis

Table 4 Subgroup analysis of the two groups (adjustment through PS regression)

		Non-antibiotic	Antibiotic	p
< 38.5 °C	Fever time^a	39.86^b	49.33^b	0.33
	Hospitalization stay [days, median(IQR)]	7 (6–9)	8 (7–10)	0.038
≥ 38.5 °C	Fever time^a	9.4^b	13.25^b	0.156
	Hospitalization stay [days, median(IQR)]	6.5 (6–9)	8 (7–12)	0.14

^aFever time was recorded as rank variables and comparison was made by Wilcoxon rank sum test
^bAverage rank; hospitalization was abnormal distribution
