CRP and endometrial cancer: However, after controlling for other factors, neither estradiol (IVW method: OR = 0.55, 95%CI = 0.04–6.94, p = 0.646) nor CRP (IVW method: OR = 0.99, 95%CI = 0.90–1.09, p = 0.814) showed statistically significant associations with endometrial cancer risk in the multivariable model, despite both showing significant associations in univariate conditional likelihood analysis (p values were 6.30 × 10−4 and 6.37 × 10−4, respectively).
