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

BK polyomavirus (BKV) infection, a common complication following kidney transplantation, can lead to BKV-associated nephropathy (BKVN). Molecular genetic studies have classified BKV into four genotypes (I-IV); however, comprehensive molecular characterization of BKV strains circulating in China remains limited. This study aimed to elucidate the predominant subtypes and clinical infection characteristics of BKV strains among kidney transplant recipients in Yunnan, a province in southwestern China. PCR-amplified BKV DNA sequences from kidney transplant recipients were aligned with reference strains and subjected to phylogenetic analysis. The viral VP1 gene was successfully amplified from 180 participants, spanning 16 ethnic groups. Genotype I was the predominant viral strain (56.66%, 102/180), followed by genotype IV (43.33%, 78/180), while genotypes II and III were not detected. Among genotypic subtypes, IVc-1 was most prevalent (40.0%, 72/180), followed by Ic (38.3%, 69/180) and Ib-1 (18.3%, 33/180). IVa-1 and IVa-2 were rare, identified in only 0.6% (n = 1) and 2.2% (n = 4) of cases, respectively. No significant differences in sex, age, BKVN incidence, BK viremia, or viruria were observed between patients with BKV-I and BKV-IV infections. Among the five confirmed BKVN cases, two were genotyped as subtype Ic, one as Ib-1, and two as IVc-1. Clinical phenotypes were also comparable between patients with BKV-I and BKV-IV infections. This study represents the largest single-center sequencing analysis of BKV in kidney transplant recipients in China, offering a valuable genomic resource for future research.
