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

Introduction: In China, no standardized single-nucleotide polymorphism (SNP) scheme exists for varicella-zoster virus (VZV) genotyping. The 5-SNP scheme with two amplicon gene fragments lacks systematic validation. This study aimed to evaluate the accuracy and applicability of this genotyping method. Methods: A total of 280 complete genomes were genotyped using 5 SNPs extracted from ORF22 (four SNPs) and ORF38 (one SNP) fragments. The results were compared with those of the phylogenetic clustering method as a reference. Concordance with reference was used to estimate the accuracy of the SNP scheme. The evaluated SNP scheme was applied to a national VZV surveillance screen containing 549 clinical samples from 17 Chinese provincial-level administrative divisions (2017-2026). Results: A 97.9% concordance was observed between the 5-SNP scheme and phylogenetic clustering methods. The 2.1% discordance was mostly attributed to putative recombination and early circulation of strains from patients with herpes zoster. During the national VZV surveillance screening, 434 samples were amplified, sequenced, and genotyped using a 5-SNP scheme. Of the genotyped samples, 90.3% and 8.8% were identified as clades 2 and 5, respectively, using four ORF22 SNPs, and the remaining 0.9% as clade 4, using ORF38 SNP. All samples showed 100% intragenotypic SNP profile consistency. Conclusion: The unified 5-SNP scheme is accurate and practical for VZV surveillance in China; however, periodic evaluation is required.
