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

The signal regulatory protein alpha (SIRPα)-CD47 axis regulates self-tolerance by delivering inhibitory signals to phagocytic cells and influencing immune responses in transplantation. This study examined the impact of SIRPα polymorphisms on CD47 binding capacity and T cell activation and analyzed the role of SIRPα genotypes in acute rejection following allogeneic liver transplantation. Peripheral blood mononuclear cells from healthy volunteers and data from liver transplant recipients were analyzed. Results showed that V2 SIRPα exhibited significantly higher CD47 binding capacity and enhanced costimulatory activity on CD4
