Further multivariate logistic regression analysis revealed that a maximum tumor diameter > 1.35 cm (odds ratio [OR] = 9.277, P < 0.001), number of tumors (OR = 2.807, P = 0.014), a CRP level > 0.39 (OR = 0.262, P = 0.017) and a PLR > 113.32 (OR = 0.210, P < 0.001) were independent variables that could predict the histological type of colorectal polyps, whereas location and physician were not (Table 3). The gene discussed is CRP; the disease is neoplasm.
