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
objectivesDespite the advances in medicine, aortic dissection remains a cardiac surgery emergency with high mortality and morbidity rates. This study examined the effects of the Glue + Felt technique, which uses biological glue and felt to repair the proximal anastomotic site, on the outcomes of patients with acute type A aortic dissection.
methodsA total of 108 patients who underwent surgery for acute type A aortic dissection at our clinic between 2007 and 2020 were included in the study. The patients were divided into two groups: the "Glue + Felt Technique" and the "Bentall-De Bono" groups, based on the surgical technique used for the aortic root. The effects of these two techniques on the development of intraoperative and postoperative complications and survival rates were statistically analyzed.
resultsThe Glue + Felt technique was used for 76 patients, while the Bentall-De Bono technique was used for 32 patients. The Kaplan-Meier analysis revealed significant differences in survival rates between the two groups over the entire follow-up period, both with and without propensity score matching (p < 0.001 and p = 0.02, respectively). However, no significant differences were observed in comparisons beyond the first 30 days of follow-up, either with or without propensity score matching (p = 0.573 and p = 0.561, respectively). The main factors contributing to this difference were the duration of cardiopulmonary bypass and aortic cross-clamp time (p < 0.05). During the average follow-up period of 46.2 ± 31.6 months, no re-intervention was required in patients from the Glue-Felt technique group.
conclusionsThe mortality rate in aortic dissection surgery is higher with more extensive surgical intervention as the duration of cardiopulmonary bypass and aortic cross-clamp time increases. Repairing the lumen and reducing operation time in suitable patients using the Glue-Felt technique for the proximal anastomotic site positively impacts postoperative complications and improves in-hospital and 30-day survival rates, without increasing long-term re-intervention rates.
