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
Serotonin (5-hydroxytryptamine, 5-HT) is a powerful modulator of neuronal activity within the central nervous system and dysfunctions of the serotonergic system have been linked to several neuropsychiatric disorders such as major depressive disorders or schizophrenia. The anterior cingulate cortex (aCC) plays an important role in cognitive capture of stimuli and valence processing and it is densely innervated by serotonergic fibers from the nucleus raphe. In order to understand how pathophysiological 5-HT signalling can lead to neuropsychiatric diseases, it is important to understand the physiological actions of 5-HT on cortical circuits. Therefore, we combined electrophysiological recordings with pharmacology and immunocytochemistry to investigate the effects of 5-HT on Somatostatin-positive interneurons (SOM-INs) and compared these to supragranular pyramidal cells (PCs). This comparison allowed us to identify common and contrasting effects of 5-HT on SOM-INs and PCs of the aCC resulting in a specific modulation of the excitation-to-inhibition balance in PCs but not in SOM-INs.
