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 use of immune checkpoint therapies targeting programmed death-1 (PD-1) and its ligand (PD-L1) continue to show limited durable success in clinical cases despite widespread application. While some patients achieve complete responses and disease remission, others are completely resistant to the therapy. Recent evidence in the field suggests that tumor-derived exosomes could be responsible for mediating systemic immunosuppression that antagonizes anti-PD-1 checkpoint therapy. In this Opinion article, we discuss our claim that endogenous tumor exosomal PD-L1 and tumor-derived exosome-induced PD-L1 are two of the most notable mechanisms of exosome-mediated resistance against antitumor immunity and we discuss how this resistance could directly influence immune checkpoint therapy failure.
