In the genetic model analysis, we found the "T" genotype of rs3783550 was associated with decreased AS risk in the dominant model (p = 0.044) and log-additive model (p = 0.023); the "C" genotype of rs3783546 was significantly associated with decreased AS risk based in the dominant model (p = 0.044) and log-additive model (p = 0.023).
With stratified analysis, the recessive models of rs3783550 (OR = 2.17, 95% CI: 1.03-4.60, p = 0.043), rs2856838 (OR = 2.58, 95% CI: 1.13-5.87, p = 0.024), rs1609682 (OR = 2.20, 95% CI: 1.04-4.65, p = 0.040), and rs3783521 (OR = 2.13, 95% CI: 1.01-4.49, p = 0.048) revealed significant relationships between these variants and an increased CRC risk only in females.
Using the chi-squared (χ<sup>2</sup>) test and genetic model analysis, we found an association with RCC risk for five SNPs [rs3783550 (IL1A), rs3783546 (IL1A), rs1609682 (IL1A), rs3783521 (IL1A), and rs1143623 (IL1B)] and increased the risk of RCC.

Of these, three SNPs (rs6542095, rs3783550 and rs3783525) also showed association with endometriosis at a nominal P < 0.05 in our independent Japanese sample.
