Sex impacts outcome in minimally invasive surgery of the ascending aorta: a propensity score matched analysis.
Article in Journal of cardiothoracic surgery, 2026. 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
backgroundMinimally invasive approaches have gained immense importance in surgery of the aortic valve, aortic root, and ascending aorta over the last decades. Despite this, data concerning impact factors of the postoperative outcome and especially investigations regarding sex-specific outcome parameters for minimally invasive aortic surgery are still lacking to date.
methodsWe present a single-center analysis of 387 patients undergoing supracoronary ascending aorta replacement, Wheat procedure, David procedure, or Bentall procedure through a minimally invasive access. A multivariate linear model was developed to identify predicting factors for a prolonged intensive care unit stay. Subsequently, the impact of the patients sex on perioperative complications and outcome as well as short- and long-term survival was investigated using a propensity score matched analysis of each 118 women and men undergoing minimally invasive ascending aortic procedures.
resultsFemale sex, patients age at operation, and operation times were identified as independent patient-specific predictors for ICU length of stay after minimally invasive ascending aortic surgery. The perioperative stroke-rate was significantly higher in women compared to men (7.6% vs. 1.7%, p = 0.031). Erythrocyte concentrate transfusion requirement was significantly higher in females (4 (IQR 2-5) vs. 2 (QR 0-4), p < 0.001). No significant differences were found between male and female patients with respect to short- and long-term survival.
conclusionsSex impacts outcome after minimally invasive ascending aortic surgery. In particular, female patients had worse short-term outcome compared to men with respect to perioperative stroke, ICU length-of-stay, and transfusion requirements.
