1 · What the graph read from it

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.

2 · The registry

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

purpose of reviewFunctional movement disorder (FMD) is a biopsychosocially-complex condition with diverse neurologic, physical, and psychiatric manifestations. Converging neuroimaging evidence demonstrates abnormalities in networks supporting self-agency, attention, sensorimotor processing, multimodal integration, salience/threat detection, and interoception. This review summarizes recent work on the prognostic and therapeutic relevance of these findings. RECENT

findingsBaseline functional neuroimaging predictors of outcome implicate cingulo-insular, frontolimbic, and subcortical circuits involved in attention, emotion regulation, and salience processing. Clinical improvement has been associated with activity changes in frontal premotor and regulatory regions, as well as in paralimbic areas. Preliminary studies of transcranial magnetic stimulation, transcranial direct-current stimulation, and neurofeedback suggest that targeted modulation of dysfunctional networks may alleviate symptoms. Neuroimaging features in FMD may inform outcome prediction, elucidate treatment-response mechanisms, and guide neuromodulation strategies. However, the field remains early in development, and larger, longitudinal studies are needed to translate these insights into routine clinical care.
