Moreover, stratified analysis suggested that patients with tumours presented significantly lower HDL-C (0.9 (0.8–1.1) mmol/L vs. 1.2 (1.0–1.4) mmol/L, p < 0.001) and ApoA1 (1.1 (1.0–1.2) g/L vs. 1.3 (1.2–1.6) g/L, p < 0.05) levels than those without tumours (Figure 3D).In addition, patients who underwent surgery had higher hsCRP levels than those without surgery (18.0 (3.4–58.5) mg/L vs. 3.0 (0.8–11.2) mg/L, p < 0.001, Supplementary Table S4). Here, APOA1 is linked to neoplasm.
