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
backgroundTo explore the genetic diversity and drug resistance status of MTB in Xuzhou, China.
methodsA total of 325 clinical MTB strains were genotyped by spacer-oligonucleotide typing (spoligotyping) and mycobacterial interspersed repetitive unit variable number of tandem repeats (MIRU-VNTR). Phenotypic resistance was assessed by drug susceptibility testing (DST).
resultBased on the spoligotyping method, 325 MTB isolates were classified into 5 known genotypes and 12 unknown genotypes, and the largest branch comprised 268 strains belonging to the Beijing family. Based on the 15-loci VNTR typing method, 325 MTB isolates were divided into 35 clusters and 220 unique patterns. Compared to the low discriminatory power of spoligotyping genotyping (HGDI = 0.3444), 15-loci VNTR genotyping had a significantly higher discriminatory power for all strains (HGDI = 0.9980), particularly for the Beijing family strains (HGDI = 0.9892). When spoligotyping and 15-loci VNTR methods were used together, the discriminatory power increased to 0.9991. The Beijing family strain presented increased risks for developing multi-drug resistance TB (
conclusionThe Beijing family isolates is the most prevalent strains in Xuzhou. Spoligotyping, in combination with 15-loci MIRU-VNTR, is useful for epidemiological analysis of MTB transmission in Xuzhou.
