Fig. 3: CAD4TB scores differ by TB but not HIV status.

CAD4TB v5 (a) and v6 (b) distributions across TB diagnostic groups: definite TB (microbiologically proven n = 99), definite TB, trace excluded (a more stringent group that excludes those whose only microbiological evidence of TB is an Xpert “trace” results, n = 75), probable TB (radiologically diagnosed, n = 172), and no evidence of TB (n = 9643). Scores in each group were stratified by HIV status (definite TB HIV-positive: n = 41, HIV-negative: n = 57; definite TB, trace excluded HIV-positive: n = 34, HIV-negative: n = 40; probable TB HIV-positive: n = 76, HIV-negative: n = 96; no TB HIV-positive: n = 2837, HIV-negative: 6755). Horizontal lines mark the median. P-values from comparisons between HIV-positive vs. HIV-negative in each diagnostic group were for definite TB: 0.26 (v5), 0.26 (v6), definite TB, trace excluded: 0.70 (v5), 0.95 (v6), probable TB: 0.88 (v5), 0.06 (v6) no TB 2.9x10-5 (v5), 0.70 (v6).
