High galectin-4 expression was significantly associated with smaller tumor size (OR = 0.43, 95% CI = 0.2–0.91, p = 0.027); by contrary, high galectin-9 expression was not significantly associated with tumor size (OR = 0.98, 95% CI = 0.7–1.39, p = 0.924) without significant heterogeneity (I2 = 0.0%, p = 0.394). This evidence concerns the gene LGALS9 and neoplasm.
