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 effect of calcification distributional density in different regions of aortic-valvular complex (AVC) on postoperative new-onset conduction block (CB) following transcatheter aortic valve replacement (TAVR) using self-expandable valves (SEV) made in China.
methodsFrom January, 2016 to December, 2022, 73 patients with severe aortic valve stenosis received Venus-A prosthetic valve replacement using SEV made in China, and postoperative new-onset CB occurred in 18 (24.7%) of the patients. The baseline data, imaging and intervention- related data were compared were between the patients with CB and those without CB. Univariate and multivariate logistic regression analysis was used for investigating the independent risk factors for new- onset CB after TAVR, and the predictive performance of these risk factors was evaluated using receiver operating characteristic (ROC) curve and DeLong test.
resultsCompared with those with CB, the patients experiencing postoperative new-onset CB had a greater implantation depth (6.77±2.45 mm
conclusionThe DLZ-LCS calcification distributional density is an independent risk factor for new-onset CB following TAVR using SEV. The conduction complications following TAVR can be effectively predicted using this calcification indicator combined with MSID.
