Isoniazid Preventive Therapy and Risk for Resistant Tuberculosis
Figure 1. Relative risk (RR) for isoniazid resistance associated with isoniazid preventive therapy in 13 studies. A) Using definition (a) of resistance for the Greenland study (20). B) Using definition (b) of resistance for the Greenland study. *Excluding the 4 studies with no resistant cases in 1 or both of the 2 groups. The squares and horizontal lines represent the relative risk (RR) and 95% confidence intervals (CIs) for each study. The diamonds represent the summary RR and 95% CIs.
