IL10 and colorectal carcinoma: The evidence supporting the association of genetically predicted circulating levels with the increased risk of CRC was revealed; these included vascular endothelial growth factor (OR = 1.352, 95% CI: 1.019–1.315, P = 0.024), interleukin-12p70 (OR = 1.273, 95% CI: 1.133–1.430, P = 4.68×10−5), interleukin-13 (OR = 1.149, 95% CI: 1.012–1.299, P = 0.028), interleukin-10 (OR = 1.230, 95% CI: 1.013–1.493, P = 0.037), and interleukin-7 (OR = 1.191, 95% CI: 1.023–1.386 P = 0.024).
