Interleukin 10 (IL-10) (−1082) polymorphism allele and genotype distribution
| IBS (n=230) | Controls (n=450) | |||
|---|---|---|---|---|
| n | % | n | % | |
| *Odds ratio (OR) 1.17 (95% confidence interval 0.93–1.49); p=0.097. | ||||
| †Fewer irritable bowel syndrome (IBS) patients of high producer (G/G) genotype (χ2=11.97, df=2, p=0.003), with more patients carrying A allele (A+: G/A or A/A) (χ2=8.08, OR 1.72 (1.18–2.50), p=0.004)‡. | ||||
| §n= number of alleles in each group, being twice the number of individuals as two alleles are inherited. | ||||
| ¶n=number of individuals with specific genotype. | ||||
