Perioperative and short-term outcomes of total arch reconstruction using a novel frozen elephant trunk stent.
Article in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesTotal arch reconstruction (TAR) for thoracic aortic dilatation increasingly incorporates frozen elephant trunk (FET) techniques. However, comparative data on the novel FET stent Fontus
methodsWe retrospectively analyzed 267 consecutive patients with thoracic aortic dilatation/aneurysms who underwent surgical procedures at our department between January 2019 and December 2024, of whom 76 were excluded (e.g., concomitant severe comorbidities, without TAR). The remaining 191 patients were grouped by stent type: C-C group (TAR with conventional CRONUS
resultsNo statistical intergroup differences were found in baseline patient characteristics. All patients recovered well with no intraoperative mortality, and no significant differences in the rate of concomitant procedures and 6-month follow-up outcomes were found in the three groups (p > 0.05). However, the operation time, CPB time, hypothermic circulation time, and SCP time were significantly longer in the C-C group, followed by the M-C group, and finally in the C-F group (p < 0.05). In addition, the C-C group exhibited the highest intraoperative blood loss and intraoperative blood transfusion, followed by the C-F group, with the M-C group showing the lowest levels. Pairwise comparisons showed these differences were statistically significant for groups C-C versus M-C and groups C-C versus C-F. Multivariate binary logistic regression showed that the operative time, CPB time, aortic cross-clamp time, and hypothermic circulatory arrest time were risk factors for postoperative pneumonia.
