Surgical techniques and prognostic nomogram for patients with supravalvular aortic stenosis.
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. 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
backgroundAn effective prognostic nomogram to predict the prognosis for supravalvular aortic stenosis (SVAS) patients is lacking.
methodsA multi-center retrospective study of consecutive SVAS patients with surgery between 2002 and 2020 was conducted. Patients underwent McGoon repairs, Doty repairs, and other repairs. The primary outcome was the re-operation or restenosis at follow-up. The nomogram based on Cox regression and Kaplan-Meier method was used to show the risk factors of the primary outcome. The predictive accuracy was determined by the concordance index (C-index) and calibration curve. The results were validated using the bootstrap resampling method.
resultsOf the 291 SVAS patients, 143 (49.1%) used McGoon repairs, 118 (40.5%) used Doty repairs and 30 (10.3%) used other repairs. The median age at operation was 4.9 years (IQR 2.3-9.9). After a median follow-up of 24 months (IQR 6.0-54.0), no difference in re-operation or restenosis was found between McGoon repairs and Doty repairs. Age, gender, SVAS type, pulmonary artery stenosis, aortic valve stenosis, sinotubular junction z-score and gradient were considered independent risk factors by Lasso regression and were included in the nomogram. The C-index of the nomogram was 0.71 (95% CI 0.61 to 0.81). The calibration curve for the probability of re-operation or restenosis showed good agreement between prediction by nomogram and actual observation.
conclusionsMcGoon repairs and Doty repairs had no difference in re-operation and restenosis risk. The proposed nomogram gave an accurate prediction of re-operation or restenosis for patients with SVAS after surgery.
