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

JAK inhibitors target a large group of cytokines that signal through the JAK-STAT pathway and are typically used clinically as immunosuppressive agents. However, recent work has demonstrated the paradoxical ability of JAK inhibitors to enhance antitumour and antiviral immune responses and established their synergy with immune checkpoint inhibitors in early-stage clinical trials. In this Perspective, we consider why JAK inhibitors, which are typically used as immunosuppressive drugs, can have immune-enhancing effects, exploring the potential mechanistic basis and the opportunities to harness this effect to improve cancer immunotherapy.
