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

The transition from well-fed to food-deprived conditions in C. elegans triggers a stereotypic exploration behaviour characterised by a temporal decrease in reorientation frequency. In this study we conduct a screen of neuropeptide mutants and identify several candidates involved in modulating this behaviour. Among these, the neuropeptide FLP-15 emerges as a key regulator. Our observations reveal that FLP-15 regulates the frequency of reversals during foraging through the I2 pharyngeal neuron via the G protein-coupled receptor NPR-3. Mutants lacking either flp-15, npr-3 or both display a significant defect in reversal frequency which does not decline temporally unlike in wild-type animals. This study also describes the expression pattern of NPR-3 in a subset of head neurons, predominantly comprising of dopaminergic neurons. Finally, flp-15 expression studies and exogenous dopamine supplementation assays reveal that FLP-15 may regulate exploratory search by modulating dopamine transmission, highlighting a novel neuropeptide-dopamine interaction involved in the control of foraging behaviours.
