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

Regulatory T cells (Tregs) are CD4(+) T cells that maintain immune homeostasis and prevent autoimmunity. Like all CD4(+) T cells, Tregs require antigen-specific signals via T cell receptor-major histocompatibility complex class II (TCR-MHCII) interactions for their development. However, the requirement for MHCII in Treg homeostasis in tissues such as intestinal lamina propria (LP) is unknown. We examined LP Treg homeostasis in a transgenic mouse model that lacks peripheral TCR-MHCII interactions and generation of extrathymic Tregs (iTregs). Thymically generated Tregs entered the LP of weanlings and proliferated independently of MHCII to fill the compartment. The adult LP was a closed niche; new thymic Tregs were excluded, and Tregs in parabiotic pairs were LP resident. The isolated LP niche was interleukin-2 (IL-2) independent but dependent on commensal bacteria. Thus, an LP Treg niche can be filled, isolated, and maintained independently of antigen signals and iTregs. This niche may represent a tissue-specific mechanism for maintaining immune tolerance.
