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
Auditory verbal hallucinations (AVH) represent a substantial therapeutic challenge in schizophrenia. Low-frequency repetitive transcranial magnetic stimulation (rTMS) has demonstrated potential in reducing AVH, yet the underlying neurobiological mechanisms remain incompletely understood. This study investigated the genetic and molecular processes associated with functional connectivity density (FCD) changes induced by 1 Hz rTMS in schizophrenia patients with AVH. The results revealed that the active stimulation group exhibited significant improvement in positive symptoms and AVH severity compared to the sham control group. Specifically, rTMS increased FCD within the frontoparietal network while decreasing FCD in the language network. Notably, baseline FCD values in these networks were predictive of the extent of symptom amelioration. Gene enrichment analysis indicated that rTMS-induced FCD changes were linked to molecular pathways critical for cellular homeostasis and neuronal function. Among the identified hub genes, GAL emerged as a key regulator of these alternations. Furthermore, neurotransmitter systems were implicated, with alterations in mu-opioid (MU) receptor density mediating the effects of GAL on FCD modifications. These findings highlight a multifaceted interplay among genetic, molecular, and connectivity-based mechanisms underlying the therapeutic efficacy of rTMS in treating AVH.
