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
Depression is one of the most common mental disorders, but its etiology remains poorly understood. Neuronal nitric oxide synthase (nNOS) has been implicated in depression, but the role of nNOS-expressing neurons is still unknown. We used chemogenetic strategies to show that nNOS-expressing neurons in the medial prefrontal cortex (mPFC) are essential for depression-related behaviors. Using electrophysiology, we determined that mPFC nNOS-expressing neurons receive projections from the posterior subregion of the paraventricular thalamic nucleus (pPVT). We show that excitatory projections from the pPVT onto mPFC nNOS-expressing neurons regulate depression-related behaviors. We further explore a mechanism in which activation of mPFC nNOS-expressing neurons leads to the subsequent release of nitric oxide (NO), which enhances the nitrosylation of cyclin-dependent kinase 5 (CDK5). Our data suggest a mechanism for depression involving excitatory pPVT projections onto nNOS-expressing neurons in the mPFC that represents a potential target for future treatments.
