In model 2, adjusted HRs (95% CIs) for 96–100% versus 0–33% YKL-40 percentile category were 2.4 (1.6–3.7) for obesity-related cancers, 2.6 (1.7–4.1) for gastrointestinal cancers, 44.2 (12.8–153.4) for liver cancer, 1.8 (0.4–8.2) for pancreatic cancer, 0.6 (0.2–1.5) for colorectal cancer, 4.2 (1.3–14.1) for bladder cancer, and 1.5 (0.5–4.4) for lung cancer (Figs. 1–2, Supplemental Table 2). Here, CHI3L1 is linked to lung cancer.
