Incidence and impact of brain lesions and cognitive impairment after CABG with moderate or severe cerebral artery stenosis seen on low-field MRI.

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
objectiveThe study aimed to assess the incidence and impact of brain lesions and cognitive impairment after coronary artery bypass grafting (CABG) in patients with moderate-to-severe cerebral artery stenosis using low-field MRI.
methods110 patients with moderate-to-severe cerebral artery stenosis who underwent CABG between November 2023 and May 2024 were enrolled. Postoperative brain lesions were evaluated using low-field MRI. Cognitive decline was defined as a reduction of ≥3 points in the Montreal Cognitive Assessment score from baseline. Risk factors associated with postoperative brain lesions and cognitive impairment were identified in univariate and multivariate logistic regression analyses.
resultsA total of 110 patients were enrolled, with a mean age of 65±7 years and 22 (20.0%) were female. New brain lesions were identified in 24 patients (21.8%). Logistic regression analysis identified operation time (OR 1.014, 95% CI 1.003 to 1.025, p=0.013) to be independently associated with brain lesions. 22.2% of the patients (20/90) experienced postoperative cognitive decline. New brain lesions were independently associated with cognitive decline (OR 4.651, 95% CI 1.158 to 18.676, p=0.030), particularly the new brain lesions impairing orientation ability (OR 4.534, 95% CI 1.438 to 14.289, p=0.010).
conclusionsLow-field MRI has proven effective in detecting new brain lesions after CABG. Both postoperative new brain lesions and CABG operation were significant contributors to cognitive decline.
