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

Ongoing thymopoiesis requires continual seeding from progenitors that reside within the bone marrow (BM), but the identity of the most proximate prethymocytes has remained controversial. Here we take a comprehensive approach to prospectively identify the major source of thymocyte progenitors that reside within the BM and blood, and find that all thymocyte progenitor activity resides within a rare Flk2(+)CD27(+) population. The BM Flk2(+)CD27(+) subset is predominantly composed of common lymphoid progenitors (CLPs) and multipotent progenitors. Of these 2 populations, only CLPs reconstitute thymopoiesis rapidly after intravenous injection. In contrast, multipotent progenitor-derived cells reconstitute the thymus with delayed kinetics only after they have reseeded the BM, self-renewed, and generated CLPs. These results identify CLPs as the major source of thymocyte progenitors within the BM.
