Forest plots illustrate the association between IL-10 gene polymorphisms and BD in Chinese Han. For each study, the odds ratio
(OR) and 95% confidence interval (CI) values are indicted. The size of each box is proportional to the weight of each study.
The squares and horizontal lines correspond to the OR and 95% CI, and the diamond represents the summary OR and 95% CI. A:
T allele versus C allele. B
: The rs3021094
A allele versus C allele. C
: The rs3790622
T allele versus C allele.
