CHI3L1 and neoplasm: Moreover, significant associations became even more obvious among the CHI3L1 risk haplotypes and clinical stage (p = 0.009; OR: 3.29, 95% CI: 1.18–9.63; ≥ stage II vs. stage I; Table 5), tumor diameter (p = 0.029; OR: 2.75, 95% CI: 0.99–8.04; >4 cm vs. ≤4 cm), and vaginal invasion (p = 0.004; OR: 4.10, 95% CI: 1.40–11.62; invasion vs. no invasion) in SCC specimens, but not in adenocarcinoma tissues.
