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
introductionMusic listening reliably induces arousal in the listener, however its effect on dopaminergic transmission is not yet fully explored. MATERIAL AND
methodsWe investigated the responsiveness of the striatal dopamine D1 receptor (D1R) system, which is preferentially engaged by phasic dopaminergic signals, using simultaneous PET-fMRI and the selective D1R radioligand [11C]SCH23390. Fifteen neurotypical participants were scanned during silence before listening to a music piece in its pleasant and unpleasantly manipulated variation. Striatal binding potential (BPND) was significantly lower when listening to music compared to silence.
resultsA seed-based fMRI analysis revealed higher functional connectivity between the striatum and left dorsolateral pre-frontal cortex (MNI: x = -43, y = 24, z = 24) during pleasant music in relation to unpleasant music. An exploratory whole-brain D1R PET analysis further identified increased insular BPND (MNI: x = -33, y = 1.5, z = 16.5; T = 5.58) during pleasant relative to unpleasant music. Comparison of BPND and fMRI beta estimates changes within that prefrontal cluster showed a moderate correlation between the pleasant and unpleasant music condition (R = -0.52, p = 0.046), but no correlation for the silent conditions (R = 0.24, p = 0.42). Changes in ratings of musical pleasantness moderately correlated with fMRI changes in the prefrontal cluster, but not with changes in BPND.
conclusionOur results demonstrate that music irrespective of valence engages the D1R system, indicating that the inherently phasic nature of music can drive D1R-related responses. Furthermore, our results demonstrate valence effects in functional connectivity between the striatum and the left dorsolateral prefrontal cortex when listening to music with varying pleasantness.
