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

CTLA-4 is constitutively expressed by CD4(+)CD25(+)Foxp3(+) Treg but its precise role in Treg function is not clear. Although blockade of CTLA-4 interferes with Treg function, studies using CTLA-4-deficient Treg have failed to reveal an essential requirement for CTLA-4 in Treg suppression in vivo. Conditional deletion of CTLA-4 in Foxp3(+) T cells disrupts immune homeostasis in vivo but the immune processes disrupted by CTLA-4 deletion have not been determined. We demonstrate that Treg expression of CTLA-4 is essential for Treg control of lymphopenia-induced CD4 T-cell expansion. Despite IL-10 expression, CTLA-4-deficient Treg were unable to control the expansion of CD4(+) target cells in a lymphopenic environment. Moreover, unlike their WT counterparts, CTLA-4-deficient Treg failed to inhibit cytokine production associated with homeostatic expansion and were unable to prevent colitis. Thus, while Treg developing in the absence of CTLA-4 appear to acquire some compensatory suppressive mechanisms in vitro, we identify a non-redundant role for CTLA-4 in Treg function in vivo.
