Multivariate survival analysis of systemic inflammatory indicators in women with breast cancer indicated that patients with high CRP [model 4: HR (95% CI) = 2.21 (1.24–3.94), P = 0.007] had a shorter OS than patients with low CRP, patients with high CAR [model 4: HR (95% CI) = 2.56 (1.46–4.47), P = 0.001] had a shorter OS than those with low CAR, and patients with high LCR [model 4: HR (95% CI) = 2.43 (1.47–4.02), P = 0.001] had a shorter OS than patients with low LCR (Table 2). Here, CRP is linked to breast carcinoma.
