Percentages do not always add up to subtotals because of rounding. Numbers shown in the table are row percentages, unless otherwise specified.
The proportion of new TB cases diagnosed varied by age (<5 years 36%, OR [compared to ≥50 years] 4.50, 95% CI 2.35–8.60; 5 to <15 years 24%, OR 2.79, 95% CI 1.61–4.83; and 15 to <50: 4%, OR 0.38, 95% CI 0.22–0.65; ≥50: 9%; overall P < .001).
