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

Although complement lysis is frequently used for the purification of lymphocyte subpopulations in vitro, how lymphocytes escape complement attack in vivo has not been clearly delineated. Here, we show that conditional gene targeting of a murine membrane complement regulator Crry on thymocytes led to complement-dependent peripheral T-cell lymphopenia. Notably, despite evidence of hypersensitivity to complement attack, Crry-deficient T cells escaped complement injury and developed normally in the thymus, because of low intrathymic complement activity. Crry-deficient T cells were eliminated in the periphery by a C3- and macrophage-mediated but C5-independent mechanism. Thus, Crry is essential for mature T-cell survival in the periphery but not for lymphogenesis in the thymus. The observation that the thymus is a complement-privileged site may have implications for complement-based antitumor therapies.
