Effect of Repetitive Transcranial Magnetic Stimulation on the Symptoms and Brain Imaging in Patients with Fibromyalgia Syndrome: A Randomized Controlled Pilot Trial.
Article in Pain and therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionRepetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral prefrontal cortex (DLPFC) has been shown to reduce the symptoms of patients with fibromyalgia syndrome (FMS). We tested whether rTMS of the left DLPFC can reduce the main symptoms in FMS and whether TMS induces changes in brain functional and structural connectivity, cortical gray matter volume, and the metabolites/neurotransmitters GABA and combined glutamate/glutamine (Glx).
methodsTwenty-seven women diagnosed with FMS according to the 2010 ACR criteria were included in a randomized controlled trial. They received either ten sessions of active or sham 10-Hz stimulation over 2 weeks embedded in a longitudinal neuroimaging setup, including one pre-treatment (T1), one post-treatment (T2), and one follow-up (T3) 3 T MRI scan. Pain and pain catastrophizing, depression, daily life/quality of life, and anxiety were assessed using standard questionnaires.
resultsLinear mixed-model analysis of clinical data showed a significant main effect of the main factor time but did not reveal group differences or group-time interactions, indicating a large placebo effect with symptom reduction in both groups. Fractional anisotropy (FA) values of the pontine crossing tract, the sagittal stratum, and the right cingulum in the active rTMS group increased between pre-TMS and the follow-up time points. Subgroup analysis of responders of the treatment group revealed higher functional connectivity between the left DLPFC and the right cerebellum. We did not find evidence for changes in the treatment group in the gray matter of the left DLPFC and for the concentrations of GABA and Glx, but a trend towards decreasing Glx levels for the factor time in all patients could be detected.
conclusionsWhile these results may be due to small sample size and short treatment duration, the findings of increased FA after active rTMS and higher functional connectivity between DLPFC and cerebellum in responders should be further explored.
