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

Type 2 immunity has evolved to protect against worms but becomes harmful when activated during allergic inflammation. Group 2 innate lymphoid cells (ILC2s) drive type 2 responses by rapidly secreting IL-5 and IL-13. The alarmins, IL-25, IL-33, and TSLP activate ILC2s and are linked to allergic diseases. However, how alarmins connect to the transcriptional networks driving type 2 effector functions remains elusive. Here, we performed RNA sequencing of ILC2s deficient in IL-25, IL-33, or TSLP pathway and identified the transcription factor Blimp-1 as an IL-33-regulated gene in ILC2s. While Blimp-1 was dispensable for ILC2 development, this transcription factor was required for type 2 cytokine production, driving eosinophilia or promoting worm expulsion. Blimp-1 deficiency resulted in reduced IRF4 expression, while Irf4-deficient ILC2s showed diminished Blimp-1 and IL-33 receptor expression, revealing a reciprocal Blimp-1-IRF4 circuit downstream of the IL-33 receptor. These findings expose the Blimp-1-IRF4 axis as an alarmin-regulated transcriptional network controlling ILC2 effector functions required for type 2 immunity.
