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

backgroundImmune cells play a pivotal role in the pathogenesis of severe pneumonia. However, the global atlas of immune cells under this condition is not fully understood.

methodsWe conducted single-cell analyses of 275 411 cells isolated from matched lung tissue, bronchoalveolar lavage fluid, and peripheral blood from 12 patients with severe pneumonia and 5 donors, in order to identify the cross-compartment sharing pattern of activated immune cells and the roles they play in severe pneumonia.

resultsOur observations revealed that activated immune cells distributed across lung interstitia and airways (alveoli; Pattern 1a), including activated tissue-resident memory-like CD8

conclusionsThe lung interstitial-to-airway/alveolar cross-compartment sharing pattern of activated immune cells (Pattern 1a) provide a robust working hypothesis for clinical and translational research for severe pneumonia.
