Interhemispheric effects of iTBS on the fronto-parietal network: Evidence from dual-site stimulation.

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
This study investigated the neuromodulatory effects of Theta Burst Stimulation (TBS) on resting-state functional connectivity (FC) following psychosocial stress induced by the Trier Social Stress Test (TSST). Given its key role in cognitive control and emotion regulation - processes highly relevant for rumination - we focused on the frontoparietal network. Across two studies, intermittent (iTBS) and continuous (cTBS) protocols were applied to the left Dorsolateral Prefrontal Cortex (DLPFC; study 1) and right Ventrolateral Prefrontal Cortex (VLPFC; study 2) prior to stress induction. Functional Near-Infrared Spectroscopy (fNIRS) was used to assess neural changes. A total of 88 (study 1) and 89 (study 2) healthy participants were recruited, balanced for low and high trait rumination. Each participant received both active and sham TBS (iTBS or cTBS), in a randomized, counterbalanced design. Results indicated that iTBS elicited excitatory effects on prefrontal and fronto-parietal connectivity, whereas cTBS effects were more variable. Trait rumination emerged as a modulator of TBS effects: In study 1, significant interactions for FC between the right VLPFC and Somatosensory Association Cortex (SAC) when stimulating the left DLPFC emerged, while study 2 revealed similar interactions for FC between the left DLPFC and SAC and intra-SAC FC when stimulating the right VLPFC. Correlations between post-stress state rumination and FC changes further support these findings. These results underscore the importance of neural assessments in TBS research and highlight the complexity of individual differences in state and trait rumination. Understanding the interplay between TBS, fronto-parietal connectivity, and rumination may provide valuable insights into personalized neuromodulation strategies.
