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

Unconventional T cells—including invariant natural killer T (iNKT) cells, mucosal-associated invariant T (MAIT) cells, and defined subsets of γδ T cells—are restricted by monomorphic major histocompatibility complex class Ib (MHC-Ib) molecules and seed tissues during development. Early-life instructive signals, including those derived from the microbiota, establish homeostatic set points for unconventional T cells, a phenomenon that has lifelong consequences for the regulation of tissue immunity, inflammation, and repair. Unconventional T cells compete for niches within tissues, and recent evidence supports the idea that the fundamental role of these cells in tissue physiology may result from their action as a network with overlapping and potentially synergistic functions, rather than as individual subsets.
