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

Both bacterial and viral infections can trigger an overwhelming host response, leading to immunopathology and organ dysfunction. Multiple studies have reported dysregulated myeloid cell states in patients with bacterial sepsis or severe SARS-CoV-2 infection. However, their relevance to viral infections other than COVID-19, the factors driving their induction, and their role in tissue injury remain poorly understood. Here, we performed a multi-cohort analysis of single cell and bulk transcriptomic data from 1845 patients across 25 studies. Our meta-analysis revealed a conserved severity-associated gene signature pointing to emergency myelopoiesis (EM) and increased IL1R2 expression in monocytes and neutrophils from patients with bacterial sepsis, COVID-19, and influenza. Analysis of tocilizumab-treated COVID-19 patients showed that IL-6 signaling blockade partially reduces this signature and results in a compensatory increase in G-CSF. To validate the role of these cytokines in vivo, we used a mouse model of influenza infection that recapitulates severity-associated increases in IL1R2+ monocytes and IL1R2
