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

CD4(-)CD8(-)double negative (DN) αβ T cells are legitimate components of the normal immune system. However, they are poorly understood and largely ignored by immunologists because of their historical association with the lymphoproliferation that occurs in mice (lpr and gld) and humans (autoimmune lymphoproliferative syndromes patients) with impaired Fas-mediated apoptosis where they are considered abnormal T cells. We believe that the traditional view that DN T cells that cause lymphoproliferation (hereafter referred to as lpr DN T cells) are CD4 and CD8 T cells that lost their coreceptor, conceived more than two decades ago, is flawed and that conflating lpr DN T cells with DN T cells found in normal immune system (hereafter referred to as nDN T cells) is unnecessarily dampening interest of this potentially important cell type. To begin rectifying these misperceptions, we will revisit the traditional view of lpr DN T cells and show that it does not hold true in light of recent immunological advances. In lieu of it, we offer a new model proposing that Fas-mediated apoptosis actively removes normally existing DN T cells from the periphery and that impaired Fas-mediated apoptosis leads to accumulation of these cells rather than de novo generation of DN T cells from activated CD4 or CD8 T cells. By doing so, we hope to provoke a new discussion that may lead to a consensus about the origin of lpr DN T cells and regulation of their homeostasis by the Fas pathway and reignite wider interest in nDN T cells.
