CRP and cancer: After adjusting for all factors, we found that higher CRP levels were associated with lower cancer survival among low income participants in the NHANES III dataset (0.22–0.99 mg/dL: HR = 1.23, 95%CI: 0.88–1.74; p = 0.22) (> 0.99 mg/dL: HR = 1.83, 95%CI: 1.10–3.04; p = 0.02), but the relationship was not significant in NHANES 1999–2002 (Table 5, Fig. 1, Supplemental Fig. 5).
