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

MDA5 is an innate immune RNA sensor that senses infection with a range of viruses and other pathogens. MDA5's RNA agonists are not well defined. Here we used single-nucleotide resolution crosslinking and immunoprecipitation (iCLIP) to study its ligands. Of note, upon infection with SARS-CoV-2 or encephalomyocarditis virus, MDA5 bound overwhelmingly to cellular RNAs. Many binding sites were intronic and proximal to Alu elements and to potentially base-paired structures. Concomitantly, cytoplasmic levels of aberrant transcripts and intron-containing unspliced transcripts increased in infected cells and displayed enrichment of MDA5 iCLIP peaks. Moreover, overexpression of the splicing factor SRSF3 reduced aberrant transcription and abrogated MDA5 activation. Taken together, we propose that MDA5 surveys RNA processing fidelity and can detect infections by sensing perturbations of post-transcriptional events such as splicing.
