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

T-helper type 2 (TH2) cells are one of the hallmarks of airway remodeling. The daunting task of regaining tolerance will be to regulate airway hyperresponsiveness (AHR) and remodeling in chronic asthma by balancing the ballet of TH1 and TH2 cells. The mechanism of tolerance appears to be modulated by a specialized subset of T cells called regulatory T cells (Tregs). Currently there are six subtypes of Tregs including CD4+CD25+ naturally occurring (N-Tregs), inducible naïve CD4+CD25- T cells (TR1), TR1 memory phenotype, T-helper type 3 (TH3), CD4-CD25+DX5+ natural killer T cells (TRNKT), and CD4-CD25+CD8+ cytotoxic T cells (TRCTC). The development of Tregs is controversial as to whether they occur in the thymus or peripheral lymphoid tissue. Studies have shown that NTregs are generated in the thymus and TR1 cells occur in the periphery. Nevertheless, Tregs express an arsenal of molecular membrane markers: CD3, CD25, CD62L, CD69, BTLA, GITR, ICOS, Neuroplin- 1 (Nrp-1), and PD-1. However, the most definitive marker is Forkhead Winged-Helix Transcriptional Factor Box p3 (Foxp3). The suppression of N-Tregs occurs by cell-to-cell contact, and low levels of IL-10 and moderate levels of TGF-beta, but the primary mechanism involves the sequestration and activation of neighboring naïve CD4+CD25- T cells to become TR1 cells. In contrast, TR1 cells exert their suppressive properties by copious secretion of IL-10 and TGF- beta. These suppressive mechanisms occur by the inhibition of IL-2 production and the promotion of cell cycle arrest. The development of this specialized subset of T cells is an enigma, but their understanding will provide a plausible panacea for asthma.
