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
objectivesTo evaluate the early clinical efficacy and safety of trans-catheter aortic valve replacement (TAVR) for patients with severe pure native aortic regurgitation (PNAR) who are not suitable for conventional surgical aortic valve replace-ment.
methodsA retrospective analysis was conducted on 48 patients with PNAR who underwent TAVR at the Department of Cardiac Surgery, the First Affiliated Hospital of Sun Yat-sen University between March 2019 and February 2025. These included 25 cases with transfemoral approach (TF-TAVR group) and 23 cases with transapical approach (TA-TAVR group). Efficacy and safety were assessed by analyzing baseline characteristics, all-cause mortality, and procedure-related complications.
resultsCompared with the TA-TAVR group, the TF-TAVR group exhibited significantly smaller aortic annulus circumference and diameter, left ventricular outflow tract circumference and diameter, diameters of the left, right, and non-coronary sinuses, and sinotubular junction (STJ) diameter, along with a shorter distance from the STJ to the aortic annular plane ring plane, a smaller annulus angle (all
conclusionsTAVR demonstrates high feasibility and acceptable safety for severe PNAR patients who are not suitable for conventional SAVR. Both TF-TAVR and TA-TAVR show comparable early postoperative efficacy and safety profiles.
