Surgical management and outcomes of coronary artery involvement secondary to acute type A aortic dissection: a retrospective cohort study.
Article in Journal of thoracic disease, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Background: Coronary artery involvement (CAI) remains a fatal comorbidity in the context of acute type A aortic dissection (ATAAD). We evaluated the impact of CAI on the perioperative and short-term outcomes of patients with ATAAD who underwent total arch replacement (TAR) and frozen elephant trunk (FET) implantation and shared our surgical management experience with the involved coronary artery. Methods: In this retrospective cohort study, a total of 204 patients with ATAAD between June 2019 and December 2021 were enrolled and divided into the CAI group (n=67) and the non-CAI group (n=137). The characteristics of CAI lesions were described according to the Neri classification. Univariable and multivariable analyses were used to identify independent risk factors for in-hospital mortality. Survival analysis was performed using the Kaplan-Meier method and compared using the log-rank test. Results: Patients in the CAI group had a longer intraoperative duration of cardiopulmonary bypass (CPB) and cross-clamp, and experienced longer mechanical ventilation time and intensive care unit stays postoperatively. Regarding perioperative outcomes, the prevalence rates of new-onset continuous renal replacement therapy requirement (23.9% Conclusions: For patients with ATAAD undergoing TAR and FET implantation, concomitant CAI may complicate surgery and increase in-hospital morbidity and mortality. CAM secondary to CAI was identified as an independent risk factor. However, short-term survival after hospital discharge was comparable between the two groups. Coronary ostium repair is quick and operable for both type A and type B lesions, while optimal management still warrants further investigation.
