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

Patients with ulcerative colitis (UC) often exhibit affective disorders, such as depression and anxiety. The underlying neurological mechanisms of these symptoms, however, remain poorly understood. This study aimed to explore alterations in functional connectivity (FC) both within and between resting-state networks (RSNs) in individuals with ulcerative colitis. Twelve meaningful RSNs were identified from 22 ulcerative colitis patients and 23 healthy controls using independent component analysis of functional magnetic resonance imaging data. Correlation analyses were performed between clinical indices, neuropsychological assessments and neuroimaging data. Compared with healthy controls, UC patients showed increased intranetwork FC, mainly located in the right temporal pole, orbitofrontal cortex, and left superior temporal and Rolandic opercular cortices within the auditory network. Increased intranetwork FC in the Rolandic opercular cortex was also observed in UC patients during remission phase, while no significant alterations were detected in patients with active-phase UC. In addition, UC patients exhibited increased connectivity between the dorsal attention and the left frontoparietal network, as well as between the anterior default mode network and the posterior default mode network, with distinct patterns of internetwork connectivity observed across different clinical phases. No significant correlations were found between altered brain regions and psychological scales in UC patients. These findings imply that UC patients may undergo functional network alterations, affecting both intranetwork connectivity within RSNs and internetwork connectivity between RSNs.
