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: Thrombotic microangiopathy (TMA), characterized by small-vessel thrombosis caused by endothelial injury, presents significant diagnostic and treatment challenges in kidney transplantation. Methods: To investigate the factors associated with posttransplant TMA, we conducted a retrospective study of 3535 kidney transplant recipients at our center from 2008 to 2023. Results: Sixty-eight patients were diagnosed with TMA, and 93% (63 of 68) underwent genetic testing. Patients were categorized into 3 groups based on the TMA etiology. Group 1 ( Conclusion: Our findings underscore the need for comprehensive pre and posttransplantation genetic testing to predict and manage the risk of TMA and prevent graft loss. CNIs may exacerbate the risk of posttransplant TMA in the presence of other complement-activating factors. Our study also highlights the importance of personalized strategies and early interventions based on the functional assessment of variants of uncertain significance (VUS).
