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

backgroundAmong the most abundant viruses in the human blood virome are anelloviruses, including alpha-, beta-, and gammatorqueviruses (TTV, TTMV, and TTMDV). Whether anelloviruses are transmitted through kidney transplantation at a young age and subsequently persist in their new host is unknown. This study investigates the dynamics and composition of the anellome in the blood of six pediatric donor-recipient pairs, with monitoring beginning before transplantation and continuing until 2 years after transplantation.

methodsDonors were sampled once, before donation, while recipients were sampled before and multiple times after transplantation (median 6.5 samples). Quantitative PCR, rolling circle amplification, Illumina sequencing, and SCANellome V2 analysis were used to detect, characterize, and compare anellovirus presence in donors and recipients.

resultsAt baseline, four out of six donors tested positive for TTV by quantitative anellovirus PCR, three of whom had sufficient viral loads to enable genomic comparison with their recipients. All recipients tested positive at baseline, five had a moderate viral load (< 10

conclusionThis finding demonstrates that anellovirus transmission from donor to recipient occurs in pediatric kidney transplantation. This may be associated with pre-existing immunosuppression.
