Olfactory inputs regulate Drosophila melanogaster oogenesis.

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.
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
Drosophila female germline development and maintenance require both local stem cell niche signaling and systemic regulation. Here, we show the indispensable function of the Drosophila melanogaster olfactory circuit in normal oogenesis and fecundity. Lack of olfactory inputs during development causes a reduction in germline stem cells. Although germline stem cells proliferate normally, the germline cysts undergo caspase-mediated apoptosis, leading to decreased follicle production and egg-laying in flies with defective olfaction. Strikingly, activation of olfactory circuits is sufficient to boost egg production, demonstrating that chemosensory-activated brain-derived inputs promote gamete development. Given the energy demands of oogenesis and its direct consequence on fitness, we propose that olfactory-stimulated systemic regulation evolved tightly with downstream diet-responsive pathways to control germline physiology in response to nutritional status. Additionally, these findings raise the possibility that sensory-mediated stem cell maintenance is a generalizable mechanism spanning a myriad of neuronal circuits, systems and species.
