1 · What the graph read from it

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.

2 · The registry

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

Early diagnosis of drug-resistant Mycobacterium tuberculosis is urgently needed to optimize treatment regimens and to prevent the transmission of resistant strains. Real-time PCR assays have been developed to detect drug resistance rapidly, but none of them have been widely applied due to their complexity, high cost, or requirement for advanced instruments. In this study, we developed a real-time PCR method based on melting curve analysis of dually labeled probes. Six probes targeting the rpoB 81-bp core region, katG315, the inhA promoter, the ahpC promoter, and embB306 were designed and validated with clinical isolates. First, 10 multidrug-resistant (MDR) strains with a wide mutation spectrum were used to analyze the melting temperature (T(m)) deviations of different mutations by single real-time PCR. All mutations can be detected by significant T(m) reductions compared to the wild type. Then, three duplex real-time PCRs, with two probes in each, were developed to detect mutations in 158 MDR isolates. Comparison of the results with the sequencing data showed that all mutations covered by the six probes were detected with 100% sensitivity and 100% specificity. Our method provided a new way to rapidly detect drug-resistant mutations in M. tuberculosis. Compared to other real-time PCR methods, we use fewer probes, which are labeled with the same fluorophore, guaranteeing that this assay can be used for detection in a single fluorescent channel or can be run on single-channel instruments. In conclusion, we have developed a widely applicable real-time PCR assay to detect drug-resistant mutations in M. tuberculosis.
