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

Autonomous regulation of the intestine requires the combined activity of functionally distinct neurons of the enteric nervous system (ENS). However, the variety of enteric neuron types and how they emerge during development remain largely unknown. Here, we define a molecular taxonomy of 12 enteric neuron classes within the myenteric plexus of the mouse small intestine using single-cell RNA sequencing. We present cell-cell communication features and histochemical markers for motor neurons, sensory neurons and interneurons, together with transgenic tools for class-specific targeting. Transcriptome analysis of the embryonic ENS uncovers a novel principle of neuronal diversification, where two neuron classes arise through a binary neurogenic branching and all other identities emerge through subsequent postmitotic differentiation. We identify generic and class-specific transcriptional regulators and functionally connect Pbx3 to a postmitotic fate transition. Our results offer a conceptual and molecular resource for dissecting ENS circuits and predicting key regulators for directed differentiation of distinct enteric neuron classes.
