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

Glycans regulate cellular function, yet how aging affects the glycocalyx remains unclear. Here, we investigate changes in immune cell glycocalyx with age and find that α2,6-linked sialic acid, a glycan epitope associated with inhibitory signaling, is down-regulated in T cells from old animals. This reduction is tightly correlated with age-associated accumulation of effector T cells, which have little to no α2,6-linked sialic acid. To understand how α2,6-linked sialic acid affects T cell physiology, we generated a mouse model with T cell-specific deletion of sialyltransferase gene
