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
This study investigates the molecular prevalence and genotypic distribution of Human Pegivirus-1 (HPgV-1) in Iranian hemodialysis (HD) patients. A case-control study was conducted from May 2017 to December 2024, including 1576 HD patients and 1000 age- and gender-matched healthy individuals. Serum samples were analyzed using nested PCR and sequencing of the 5'-UTR region to detect HPgV-1 RNA and determine genotypes. The prevalence of HPgV-1 was significantly higher in HD patients (13.6 %) compared to healthy controls (0.6 %). Among HPgV-1-positive HD patients, only genotype 2a was identified. Co-infections were notable, with 11.8 % of HPgV-1-positive patients also infected with HCV (predominantly genotype 3a), 3.0 % with HBV, and 11.7 % with HIV. Interestingly, HCV co-infected patients exhibited lower liver enzyme levels, while those co-infected with HIV had significantly higher CD4+ T cell counts (605.2 ± 198.7 vs. 412.3 ± 156.8 cells/mm³, P < 0.001), suggesting potential immunomodulatory effects of HPgV-1. Additionally, factors such as prolonged dialysis duration, elevated urea levels, and older age were significantly associated with HPgV-1 positivity. These findings underscore HD as a major risk factor for HPgV-1 transmission, likely exacerbated by hospital-acquired practices in dialysis units. The observed associations between HPgV-1 and improved clinical parameters in co-infected individuals highlight its complex role in viral pathogenesis, warranting further investigation into its underlying mechanisms. This study emphasizes the urgent need for stringent infection control measures in dialysis settings to mitigate viral transmission.
