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
background and purposeFibromyalgia (FM) is a chronic syndrome characterized by widespread musculoskeletal pain, hypersensitivity, and cognitive impairments. Alterations in brain functional connectivity have been suggested as possible mechanisms underlying pain amplification in these patients. This study aimed to investigate patterns of brain functional connectivity in patients with FM using resting-state functional magnetic resonance imaging.
methodsData were obtained from the public OpenNeuro repository and acquired on a 3 Tesla scanner. The sample consisted of 33 women with a clinical diagnosis of FM (x̅ = 41.73 ± 6.09 years) and 33 age-matched healthy controls (x̅ = 41.52 ± 6.03 years), with no significant differences in age (p = 0.89) or education level (p = 0.81). Images were processed and analyzed using independent component analysis. Between-group comparisons were corrected for multiple comparisons using false discovery rate (FDR) correction (p < 0.05).
resultsPatients with FM showed a significant reduction in functional connectivity within the right sensorimotor network (SMN) compared to controls (p-FDR < 0.05). Moreover, a negative correlation was observed between connectivity in this network and the sensory dimension of pain assessed by the McGill Pain Questionnaire (r = -0.35; p = 0.05).
conclusionThe reduced functional connectivity within the SMN may represent a neurobiological marker of FM, reflecting dysfunctions in sensorimotor integration and central modulation of pain. These findings support the hypothesis that FM involves functional brain alterations related to pain perception and amplification.
