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

The thymus contains various antigen-presenting cells, including B cells, which remain activated even under steady-state conditions, suggesting ongoing local stimulation. In this study, we identify class-switched memory B cells in the thymus. Some of these cells switch their immunoglobulin to IgG2b and IgA, and express typical memory markers CD73 and PD-L2. Memory B cell differentiation in the thymus begins in neonatal mice, preceding the appearance of class-switched B cells in other peripheral lymphoid organs. Notably, exposure to environmental antigens does not influence their differentiation. Additionally, cognate interaction with CD4
