After adjusting for independent variables with P < 0.5 and some other relative parameters in the regression model, including age, sex, BMI, ASA score, diagnosis, diabetes, heart disease, COPD, Hb, CRP, ESR, WBC, and serum albumin, the bacteriuria-positive group had a significantly increased risk of superficial wound infection (OR = 7.587, 95%CI: 2.002 to 28.755, P = 0.003, Table 5), wound leakage (OR = 3.044, 95%CI: 1.461 to 6.342, P = 0.003, Table 6), and readmission (OR = 4.410, 95%CI: 1.485 to 13.097, Table 7) relative to those who had negative bacteriuria results. Here, CRP is linked to diabetes mellitus.
