Figure 3: Forest plot for meta-analysis showing the risk of tuberculosis in five different ethnic groups with interferon-gamma +874 T/A polymorphism through dominant model (AA vs. AT + TT). (a) Asians; (b) East Asians; (c) Europeans; (d) Americans; and (e) Africans. The horizontal line on the forest plot represents 95% confidence interval and the small vertical lines crossing this horizontal line represents odds ratio. The red bars represent relative weight given to each study and the yellow row illustrates Pooled odds ratio with 95% confidence interval. Significant association was found between AA Genotype of +874 T/A polymorphism and tuberculosis in all ethnic groups except Asian
