Figure 3. Forrest plot showing the study-specific and pooled estimates of incidence rate ratios (RR) for tuberculosis (TB) among health care workers (HCWs) compared with the corresponding general populations, by TB incidence group according to the World Health Organization. Studies are sorted by incidence category: low, <50 cases/100,000 population; intermediate, 50–99 cases/100,000 population; high, >100 cases/100,000 population. CI, confidence interval.
