Relationship between HLA-DR gene polymorphisms and outcomes of hepatitis B viral infections: A meta-analysis

Figure 2 Forest plots of pooled odd ratio with 95% confidence interval for associations between human leukocyte antigens-DR polymorphisms and clearance of chronic hepatitis B virus infection. The fixed-effects model was constructed using the Mantel-Haenszel’s method. Subgroup meta-analysis was conducted based on ethnicity (Chinese Han group and other ethnic groups). The squares and horizontal lines correspond to the study-specific odd ratio (OR) and 95% confidence interval (95% CI); the box size is proportional to the meta-analysis study weight, the diamonds represent the pooled OR and 95% CI. HLA: Human leukocyte antigens.
