Positive predictive value (PPV) of a rifampicin resistance signal on Xpert MTB/RIF among presumptive TB patients tested, during the intervention phase at all 18 treatment units.

*If results are available for both phenotypic DST and LPA, a rifampicin resistance result on at least one of those is considered as confirmatory§Adjusted for clustering at site level using robust standard errorsAbbreviations: PPV = Positive Predictive Value; LPA = Line probe assay; Culture DST = phenotypic drug susceptibility testing; PTB = pulmonary TB; Rif Res = Rifampicin resistance; DR suspect = number of presumptive pulmonary drug resistance TB patients tested, TB suspect = number of presumptive pulmonary TB patients testedPositive predictive value (PPV) of a rifampicin resistance signal on Xpert MTB/RIF among presumptive TB patients tested, during the intervention phase at all 18 treatment units.
