In our study, the WBC and neutrophil count, MDW, and CRP levels were higher in the complicated colonic diverticulitis group (p < 0.05, Table 1); however, only the MDW was found to have a statistically significant association with complicated diverticulitis in the multivariable binary logistic regression analysis (p < 0.001, Table 2). Here, CRP is linked to diverticulitis of colon.
