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

backgroundAntibody-mediated rejection (AMR) in pediatric liver transplantation (LT) is uncommon and poorly understood. While human leukocyte antigen (HLA) antibodies are usually implicated in AMR, non-HLA antibodies have also been reported.

methodsWe describe a 7-year-old female with non-HLA AMR in the setting of positive angiotensin type 1 receptor (AT1R) antibodies.

resultsShe was diagnosed with acute T-cell mediated rejection (TCMR) 6 months post-LT which was treated with intravenous methylprednisolone (IVMP) but had minimal response. A repeat biopsy revealed features of AMR including C4d staining and capillaritis, but donor-specific antibodies (DSAs) were negative. However, AT1R antibodies were elevated at 21 U/mL. She received antithymocyte globulin (ATG) and was started on losartan to block AT1R antibodies, with excellent response.

conclusionWhile the recognition and mechanisms of AMR in pediatric LT are in its infancy, this case highlights the importance of considering non-HLA antibodies as potential mediators of AMR. Children who fail to respond to TCMR treatment should be evaluated for AMR by obtaining DSAs, C4d staining on biopsy, and non-HLA antibodies.
