Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.
Questions and results
Cough for two weeks or more
Population: of people with HIV‐negative or unknown HIV status who are considered eligible for systematic screening for tuberculosis disease. Role of index test: individuals with a positive screening test are offered further confirmatory testing to establish a tuberculosis diagnosis. Reference standards: any one or combination of mycobacterial culture (on solid or liquid medium), sputum smear microscopy, Xpert MTB/RIF, or other nucleic acid amplification test. Study design: cross‐sectional studies. Cough for two weeks or more summary sensitivity (95% CI): 42.1% (36.6 to 47.7); summary specificity (95% CI): 94.4% (92.6 to 95.8)
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Index test result | no estimate extracted | 0 participants | Ungraded |
True positives (participants with tuberculosis disease) | no estimate extracted | 2 participants | Very low Downgraded: risk of bias, inconsistency |
False negatives (participants incorrectly classified as not having tuberculosis disease) | no estimate extracted | 3 participants | Very low Downgraded: risk of bias, inconsistency |
True negatives (participants without tuberculosis disease) | no estimate extracted | 939 participants | High |
False positives (participants incorrectly classified as having tuberculosis disease) | no estimate extracted | 56 participants | High |
Cough of any duration (any cough)
Population: of people with HIV‐negative or unknown HIV status who are considered eligible for systematic screening for tuberculosis disease. Role of index test: individuals with a positive screening test are offered further confirmatory testing to establish a tuberculosis diagnosis. Reference standards: any one or combination of mycobacterial culture (on solid or liquid medium), sputum smear microscopy, Xpert MTB/RIF, or other nucleic acid amplification test. Study design: cross‐sectional studies. Cough of any duration summary sensitivity (95% CI): 51.3% (42.8 to 59.7); summary specificity (95% CI): 87.6% (81.6 to 91.8)
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Index test result | no estimate extracted | 0 participants | Ungraded |
True positives (participants with tuberculosis disease) | no estimate extracted | 3 participants | Very low Downgraded: risk of bias, imprecision, inconsistency |
False negatives (participants incorrectly classified as not having tuberculosis disease) | no estimate extracted | 2 participants | Very low Downgraded: risk of bias, imprecision, inconsistency |
True negatives (participants without tuberculosis disease) | no estimate extracted | 871 participants | Low Downgraded: risk of bias, imprecision, inconsistency |
False positives (participants incorrectly classified as having tuberculosis disease) | no estimate extracted | 124 participants | Low Downgraded: risk of bias, imprecision, inconsistency |
Any tuberculosis symptom
Population: of people with HIV‐negative or unknown HIV status who are considered eligible for systematic screening for tuberculosis disease. Role of index test: individuals with a positive screening test are offered further confirmatory testing to establish a tuberculosis diagnosis. Reference standards: any one or combination of mycobacterial culture (on solid or liquid medium), sputum smear microscopy, Xpert MTB/RIF, or other nucleic acid amplification test. Study design: Cross‐sectional studies. Any tuberculosis symptom summary sensitivity (95% CI): 70.6% (61.7 to 78.2); summary specificity (95% CI): 65.1% (53.3 to 75.4)
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|

True positives (participants with tuberculosis disease) | no estimate extracted | 4 participants | Very low Downgraded: risk of bias, imprecision, inconsistency |
False negatives (participants incorrectly classified as not having tuberculosis disease) | no estimate extracted | 1 participants | Very low Downgraded: risk of bias, imprecision, inconsistency |
True negatives (participants without tuberculosis disease) | no estimate extracted | 648 participants | Low Downgraded: risk of bias, imprecision, inconsistency |
False positives (participants incorrectly classified as having tuberculosis disease) | no estimate extracted | 347 participants | Low Downgraded: risk of bias, imprecision, inconsistency |
Any CXR abnormality
Population: of people with HIV‐negative or unknown HIV status who are considered eligible for systematic screening for tuberculosis disease. Role of index test: individuals with a positive screening test are offered further confirmatory testing to establish a tuberculosis diagnosis. Reference standards: any one or combination of mycobacterial culture (on solid or liquid medium), sputum smear microscopy, Xpert MTB/RIF, or other nucleic acid amplification test. Study design: cross‐sectional studies. Any CXR abnormality summary sensitivity (95% CI): 94.7% (92.2 to 96.4); summary specificity (95% CI): 89.1% (85.6 to 91.8)

False positives (participants incorrectly classified as having tuberculosis disease) | no estimate extracted | 108 participants | Low Downgraded: risk of bias, imprecision, inconsistency |
CXR abnormalities suggestive of tuberculosis
Population: of people with HIV‐negative or unknown HIV status who are considered eligible for systematic screening for tuberculosis disease.
