MUC16 and brain infarction: logit p = −9.964 + 1.006X1 + 1.016X2 + 1.025X3.Using this equation, the D-dimer level (odds ratio [OR]: 1.006 per 1 ng/mL increase; 95% confidence interval [CI]: 1.004–1.009; P = .000), CA125 level (OR: 1.016 per 1 U/mL increase; 95% CI: 1.005–1.027; P = .005), and the PNR (OR: 1.025 per 1 point increase; 95% CI: 1.003–1.048; P = .023) were identified as independent risk factors for cerebral infarction in patients with GC (Table 2).
