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

Resistance to anti-PD-1/PD-L1 immune checkpoint blockade continues to be a critical challenge undermining its therapeutic efficacy in clinical applications. Most of the resistance mechanisms characterized to date have predominantly involved external factors beyond PD-L1. Here, we unexpectedly discovered that PD-L1 itself possesses E3 ubiquitin ligase activity to induce β2m ubiquitylation and subsequent degradation, which notably reduces MHC-I levels on the surface of tumor cells and antigen-presenting cells, thereby contributing to tumor cell evasion of recognition by CD8
