Quantitative study on whole brain volume in patients with obstructive sleep apnea based on synthetic magnetic resonance imaging.
Article in BMC medical imaging, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo apply SyMRI to quantify whole brain volume changes in patients with varying degrees of obstructive sleep apnea (OSA).
methodsA total of 49 untreated adult patients diagnosed with OSA via polysomnography (PSG) at our hospital were included in this study. Among these patients, 21 were categorized into the mild-to-moderate OSA group, and 28 into the severe OSA group. Additionally, 31 healthy adults were recruited as the healthy control (HC) group. SyMRI post-processing software was used to obtain whole brain volume segmentation values.
resultsIn terms of the STOP-BANG questionnaire, the score of the severe OSA group was significantly higher than that of the mild-to-moderate OSA group (P < 0.05). Compared with the HC group, the mild-to-moderate OSA group and the severe OSA group exhibited a reduction in N3-stage sleep (both P < 0.05). Post-hoc multiple comparisons showed that compared with the HC group, the severe OSA group had increased GMV, BPV, and ICV, while the mild-to-moderate OSA group showed an increase in CSFV (P < 0.05). Additionally, compared with the HC group, the mild-to-moderate OSA group exhibited a decrease and the severe OSA group showed an increase in MYV (P < 0.05). Multiple comparisons of normalized volume fractions revealed that GMF, WMF, CSFF, MYF and BPVF were significantly different between the HC group and OSA groups (all P < 0.05).
conclusionThe brain volume parameters generated from SyMRI can quantify the degree of brain injury in patients with OSA. CLINICAL TRIAL NUMBER: Not applicable.
