OFC-induced network modularity improves positive symptoms and attentional alertness in schizophrenia: a combined rTMS-fMRI study.
Trial report in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Repetitive Transcranial Magnetic Stimulation (rTMS) targeting the orbitofrontal cortex (OFC) has emerged as a promisingerapeutic option for drug-naïve people with schizophrenia (SCZ). However, the putative underlying mechanisms of OFC-induced physiological effects remain unknown. In this completed randomized, double-blind, placebo-controlled trial (ChiCTR2000041106), we delivered 4 weeks of low-frequency rTMS to the right OFC in SCZ, with participants receiving either active or sham stimulation, and followed a network neuroscience framework to explore the alteration of dynamic modularity induced by the OFC. The trial met its pre-specificized primary endpoint following active treatment. Neuroimaging analysis reported here were secondary outcomes. We found that the modularization between OFC and the default mode network (DMN) across time windows supported improvements in symptoms and cognitive function. This dynamics pattern was spatially constrained, with stronger rTMS modulation observed in DMN regions centered on the ventromedial prefrontal cortex (vmPFC). The spatial topography of this pattern was correlated with the expression of schizophrenia-related genes and markers of excitatory neurotransmission, supporting its biological relevance. Crucially, such cascade of physiological effects was specifically linked to improvements in cognitive attention/vigilance and were modulated by their positive symptoms. Exploratory analyses showed that OFC-induced modularity weakened the DMN's causality over the downstream attention network. These findings reveal the important role for the dynamic modularity of the OFC as an "intermediate phenotype" mediating the pathway from genetic variation to behavioral manifestations, highlighting the potential of low-frequency stimulation of the OFC as a therapeutic strategy for specific subgroups of SCZ, especially those with positive symptoms and attention deficits.
