The Change of Laboratory Tests Could Be Predictive Factors for Infection after McKeown Esophagogastrectomy

Table 5

Receiver operating characteristics of the independent risk factors and the scoring system.

Factors	AUC (95% CI)	value	Cut-off	Sensitivity (%)	Specificity (%)
Change of WBC level	0.575 (0.498–0.651)	0.039	4.420	61.1	53.8
Change of glucose level	0.725 (0.660–0.790)	<0.001	4.355	62.5	74.8
Change of ALB level	0.658 (0.590–0.727)	<0.001	−11.900	59.7	67.1
Scoring system	0.843 (0.793–0.894)	<0.001	2.5	70.8%	85.3%

Statistically significant at . Change of ALB: serum ALB level within 24 h after surgery minus pre-operation. Change of WBC level: serum WBC level within 24 h after surgery minus pre-operation. Change of glucose: blood glucose level within 24 h after surgery minus pre-operation. With regard to the scoring system, patients were assigned a score of 1 for each of the following factors: poor coughing ability, smoking habit, change of WBC count and blood glucose levels greater than the cut-off values, and change of ALB level lower than the cut-off value, whereas patients who did not meet these requirements were assigned a score of 0 each.
