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
objectiveMinimally invasive coronary artery bypass grafting (MICS CABG) via an anterolateral mini-thoracotomy represents a viable and safe approach. However, the proximal anastomosis of the saphenous vein to the ascending aorta can be technically challenging, particularly in cases with a prominent right ventricular outflow tract or pulmonary artery. In this report, we present an enhanced proximal anastomosis technique for minimally invasive coronary artery bypass grafting performed via intercostal thoracotomy.
methods45 patients with a mean age of 64.6 ± 9.0 years underwent minimally invasive coronary artery bypass grafting with enhanced technique via intercostal thoracotomy between July 2021 and November 2023. Multilevel pericardial retractions were employed to laterally displace the heart and a flexible side-biting clamp was placed on the ascending aorta via a 1-cm incision in the left second intercostal space, enabling handsewn proximal anastomoses on the ascending aorta.
resultsThe mean number of grafts was 2.8 ± 0.5, with a total of 11 patients (24%) had 2 grafts, 32 patients (71%) had 3 grafts, and 2 patients (4%) had 4 grafts. Median operative time was 4.2 ± 0.7 h, mean intensive care unit stay was 1.5 ± 0.5 days, and mean in-hospital stay time was 9.1 ± 6.0 days. No in-hospital mortality occurred.
conclusionThis technique provides a reliable approach for overcoming technical limitations of proximal anastomosis in MICS CABG, especially when aortic access is problematic.
