The percentages are based on all patients (N = 322) as the denominator. Sputum includes study TB screening and routine clinical samples.
Abbreviations: TB, tuberculosis; TB-LAM, Determine TB-LAM Ag assay; Xpert, Xpert MTB/RIF assay.
aCerebrospinal fluid (CSF) testing consistent with TB includes lymphocytes with raised protein or positive Xpert. One patient was missing data for CSF testing. TB score was calculated based on the number of positive urine TB tests (TB-LAM or Xpert, possible values 0–2).
