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

A major goal of biomedical research is to assign functions to the myriad alternative RNA and protein isoforms. This challenge is particularly relevant to the mammalian nervous system, which produces complex repertoires of alternative splicing events. Here, we describe CHyMErA-seq, a platform that couples systematic deletion of exons to a single cell transcriptomics read-out, and apply this method to investigate a critical program of brain-specific microexons. Perturbation of microexons during neurogenesis reveals convergent roles in the temporal regulation of gene expression programs that direct signaling pathways and morphogenesis. We further observe microexons, including those in the Bin1, Clasp1, Gfra1, Med23, Ptprf and Ralgapb genes, that are required for the correct timing of autism-linked gene expression. Collectively, we describe a flexible system for isoform-resolution perturbation at a single cell level, together with insights into the roles of microexons in the developmental timing of neurogenesis transcriptomic signatures linked to brain disorders.
