Figure 5: Forest plot for metaanalysis showing extrapulmonary tuberculosis risk in different ethnic groups with interferongamma + 874 T/A polymorphism through heterozygous model (AA vs. AT). (a) Asians; (b) East Asians; (c) Americans; and (d) 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 + 874 T/A polymorphism (AA Genotype) and extrapulmonary tuberculosis in Asians, East Asians and Africans
