CRP and Increased total leukocyte count: As a result of the multiple logistic regression analysis, including the variables that were found significantly associated in the univariate analyses initially, CRP > 0.5 mg/dL (odds ratio (OR): 1.595, 95% confidence interval (CI): 1.090–2.335, p = 0.016), leukocytosis > 10,000/mm3 (OR: 1.952, 95% CI: 1.459–2.610, p < 0.001), and proteinuria (OR: 2.669, 95% CI: 1.507–4.726, p = 0.001) were found significantly associated with GIS involvement (Table 4).
