Real-time multispectral imaging for intraoperative monitoring of coronary artery bypass graft patency.
Article in Journal of biomedical optics, 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
Significance: Coronary artery disease is the leading cause of death worldwide, accounting for 16% of all deaths. A common treatment is coronary artery bypass grafting (CABG), though up to 12% of bypass grafts fail during surgery. Early detection of graft failure by intraoperative graft patency assessment could prevent severe complications. Aim: We aim to evaluate multispectral imaging (MSI) as a non-invasive, contrast-free method for assessing graft patency during CABG surgery. Approach: MSI was conducted at video rate during three CABG surgeries and two control surgeries. Two multispectral snapshot cameras captured images in the visible and near-infrared range. Tissue oxygenation and perfusion were derived using linear spectral unmixing and spectral indices. Results: Significant increases in both oxygenation ( Conclusions: MSI could offer a valuable tool for surgeons, helping to reduce the risk of graft failure and improve patient outcomes.
