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

The Haarlem genotype is a significant yet understudied part of the Euro-American lineage of Mycobacterium tuberculosis, characterized by unique pathogenetic features. Spoligotyping is a primary method for its detection, but it is not suitable for isolates with long blocks of deleted spacers. We have developed a simple and robust method to detect the Haarlem genotype. The real-time PCR (RT-PCR) assay with LNA probes was designed to detect the Rv0282 211 C > T mutation that was shown to be specific for the Haarlem genotype. The developed RT-PCR assay was optimized with 68 isolates with known whole-genome sequencing (WGS) data and applied to the geographically and genetically diverse collection of 428 isolates. As a result, 396 isolates were concordantly assigned to either Haarlem or non-Haarlem genotypes by both methods, whereas 32 isolates were discrepant cases. Twenty-two isolates of "unknown genotype" (Russia, Belarus, and Poland) were assigned to Haarlem by SNP-based assay. WGS of these isolates confirmed the results of the RT-PCR assay. To conclude, the developed RT-PCR method provides a reliable detection of the Haarlem genotype in retrospective collections and under prospective epidemiological surveillance. Its actual proportion in M. tuberculosis populations in certain world regions is higher than previously thought. Abridged spoligoprofiles with large deleted blocks of spacers require caution in interpretation.
