A rapid identification technique for drug-resistant
Article in Bioinformation, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The emergence of multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) strains is a major health problem for high Tuberculosis (TB) incidence countries. Therefore, it is of interest to identify antibiotic resistant bacteria by mismatch detection using DNA hybridization. We generated PCR products for five genes (rpoB, inhA, katG, gyrA and rrs) associated with drug resistance TB from MDR and XDR Mycobacterium tuberculosis (MTB) DNA samples. These were hybridized to PCR products from MTB H37Rv (pansusceptible laboratory strain) to generate DNA hetero-duplex products, which was digested by Detection Enzyme (GeneArt Genomic Cleavage Detection Kit) and visualized by agarose gel electrophoresis. Results show different bands with sizes of 400 bp and 288 bp (rpoB), 280 bp (inhA), 310 bp (katG), 461 bp (gyrA) and 427 bp (rrs) suggesting mutations in DNA heteroduplex for each gene. Detection Enzyme specifically cleaves DNA hetero-duplex with mismatch. The technique helps in the improved detection of MDR (mutations in rpoB, inhA and katG) and XDR (mutations in rpoB, inhA katG, gyrA and rrs) MTB strains. Moreover, the technique is customized without expensive specialized equipment to detect mutations. It is also fast, efficient and easy to implement in standard molecular biology laboratories.
