Long-term outcomes after bentall-de bono versus modified bentall-de bono procedures: 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
objectiveTo evaluate the impact of Bentall-de Bono (BD) versus modified Bentall-de Bono (MBD) procedures on patient survival and long-term clinical outcomes.
methodsWe reviewed 1,478 patients who underwent Bentall procedures between 2003 and 2022. Patients were initially stratified into two groups based on surgical technique: the BD group (n = 1,274), and the MBD group (n = 204). To mitigate baseline imbalances and selection bias, a 1:1 propensity score matching analysis was performed, yielding 202 matched pairs. Long-term survival was assessed using Kaplan-Meier analysis. Stroke was analyzed as an exploratory secondary cerebrovascular outcome. Predictors of mortality were identified via multivariable Cox proportional hazards regression.
resultsIn the matched cohort, the median follow-up was 5.98 (interquartile range: 3.53-9.84) years. Kaplan-Meier analysis demonstrated comparable 10-year survival rates between the BD and MBD groups (90.9% vs. 88.4%, P = 0.42). Freedom from stroke was evaluated exploratorily and did not differ significantly between groups. (80.0% vs. 80.2%, P = 0.63). Multivariable Cox regression confirmed that the surgical technique (BD vs. MBD) was not an independent predictor of long-term mortality (hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.40-1.74; P = 0.634). Independent predictors of late mortality included advanced age and prolonged aortic cross-clamp time.
conclusionThere is no difference in long-term survival following BD versus MBD.
