Retrospective cohort development and internal validation of a prediction model for 30-day mortality after TEVAR in type B aortic dissection.
Article in International journal of surgery (London, England), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundType B aortic dissection (BAD) carries substantial 30-day mortality despite advances in thoracic endovascular aortic repair (TEVAR), yet individualized prediction tools are lacking.
methodsIn this retrospective single-center study, 1011 consecutive patients with BAD undergoing TEVAR from January 2014 to December 2024 were randomly split 70:30 into training ( n = 708) and validation ( n = 303) cohorts. Pre- and intraoperative variables - including chronic kidney disease (CKD), admission systolic blood pressure (SBP), malperfusion syndrome, d -dimer, creatinine, maximal descending aortic diameter (Max DAD), dissection extent, and false-lumen thrombosis status - were analyzed. Variables with P < 0.05 in univariable analysis entered multivariable logistic regression to identify independent predictors. A nomogram was constructed from final coefficients, and model performance was evaluated by area under the receiver-operating characteristic curve (AUC), calibration, and decision-curve analysis (DCA).
resultsThe overall 30-day mortality was 6.5%. Independent predictors included CKD, higher SBP, malperfusion syndrome, elevated d -dimer, higher creatinine, larger Max DAD, thoracoabdominal extent, and incomplete false-lumen thrombosis. The nomogram yielded an AUC of 0.92 (95% confidence intervals 0.88-0.96) in the training cohort and 0.91 (0.87-0.95) in the validation cohort, with good calibration and net benefit on DCA.
conclusionsThis nomogram accurately predicts 30-day mortality after TEVAR in patients with BAD and may inform individualized perioperative risk stratification. External validation and prospective evaluation are warranted.
