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
introductionSurgical treatment of the aortic valve represents the gold standard, and thus aortic valve replacement (AVR) is one of the most commonly performed cardiac operations.
aimTo evaluate the early outcome of aortic valve replacement with the Perceval S sutureless aortic bioprosthesis. MATERIAL AND
methodsThis was a retrospective analysis of 24 patients (mean age: 71 ±5 years), who underwent aortic valve replacement with a Perceval S valve. Concomitant coronary artery bypass grafting (CABG) was performed in 9 patients. Patients were evaluated preoperatively, at hospital discharge, and once during follow-up.
resultsA total of 15 of 24 patients underwent isolated sutureless aortic valve replacement (mean aortic cross-clamp time: 60 ±14 minutes; mean bypass time: 90 ±23 minutes). Coronary bypass grafting was performed in 9 patients (mean aortic cross-clamp time: 78 ±23 minutes; mean bypass time: 111 ±31 minutes). Hospital mortality was nil. Mean and peak transvalvular pressure gradients were 10 ±2 mm Hg and 21 ±3 mm Hg at follow-up, respectively. Moderate or severe aortic regurgitation did not develop in any patients during the follow-up period. No valve thrombosis, thromboembolic events, or structural valve deterioration were observed.
conclusionsIn our experience with sutureless aortic valve replacement, the surgical procedure is shown to be safe. The early haemodynamic performance seems favourable. By shortening the aortic cross-clamp and bypass times we can notice advantages, especially in high-risk patients. Minimally invasive access seems to be facilitated. Larger studies are needed to confirm our data and determine the long-term durability of the Perceval S sutureless bioprosthesis.
