CRP and cancer: In multivariate analysis including continuous CRP, IL‐6, YKL‐40, CEA, CA 19‐9, age, sex (dichotomized), BMI (categorised), PS, CCI and a former cancer diagnosis (dichotomized), CRP (OR = 1.28, 95% CI 1.12–1.47, p < 0.001), CEA (OR = 1.61, 1.41–1.98, p < 0.001), CA 19‐9 (OR = 1.15, 1.03–1.29, p = 0.014), a 10‐year increase in age (OR = 1.29, 1.02–1.63, p = 0.037) and BMI 25–30 (OR = 1.80, 1.14–2.83, p = 0.010) were associated with a cancer diagnosis (Figure 2B).
