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

Immunity against new infections declines in the last quartile of life, as do numbers of naive T cells. Peripheral maintenance of naive T cells over the lifespan is necessary because their production drastically declines by puberty, a result of thymic involution. We report that this maintenance is not random in advanced aging. As numbers and diversity of naive CD8(+) T cells declined with aging, surviving cells underwent faster rates of homeostatic proliferation, were selected for high T-cell receptor:pMHC avidity, and preferentially acquired "memory-like" phenotype. These high-avidity precursors preferentially responded to infection and exhibited strong antimicrobial function. Thus, T-cell receptor avidity for self-pMHC provides a proofreading mechanism to maintain some of the fittest T cells in the otherwise crumbling naive repertoire, providing a degree of compensation for numerical and diversity defects in old T cells.
