Broad-range PCR coupled with mass-spectrometry for the detection of Mycobacterium tuberculosis drug resistance.
Article in Germs, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe need to limit the spread of drug-resistant Mycobacterium tuberculosis requires rapid detection of resistant strains. The present study aimed to evaluate a commercial assay using broad-range PCR coupled with electrospray ionization mass spectrometry (PCR/ESI-MS) for the rapid detection of isoniazid (INH) and rifampin (RIF) resistance in M. tuberculosis strains isolated from Romanian patients with pulmonary tuberculosis.
methodsPCR/ESI-MS was used to detect genotypic resistance to RIF and INH in a panel of 63 M. tuberculosis isolates phenotypically characterized using the absolute concentration method on Löwenstein-Jensen medium.
resultsThirty-eight (60%) strains were susceptible to both drugs, 22 (35%) were RIF and INH resistant, one was INH mono-resistant and two were RIF mono-resistant. The sensitivity for INH and RIF resistance mutations detection were 100% and 92% respectively, with a specificity of more than 95% for each drug.
conclusionPCR/ESI-MS is a good method for the detection of RIF and INH resistance and might represent an alternative to other rapid diagnostic tests for the detection of genetic markers of resistance in M. tuberculosis isolates.
