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 identify the risk factors for vascular complications after total cerebral angiography by trans-radial access (TRA) in elderly cerebrovascular accident (CVA) patients and develop a predictive model.
methodsData from 248 elderly CVA patients at Lianyungang Affiliated Hospital from December 2021 to March 2024 were retrospectively analyzed. The patients were divided into two groups: complicated (those with vascular complications) and non-complicated (those without vascular complications). Clinical data were collected and analyzed. Risk factors were identified using multifactorial logistic regression.
resultsA total of 62 patients experienced vascular complications. Independent risk factors included intraoperative heparin dosage, number of radial artery punctures, timing of surgery, surgical time, mode of pressure hemostasis, duration of pressure hemostasis, and postoperative HAS-BLED (hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, drugs/alcohol concomitantly) score (P<0.05). The nomogram model for predicting complications showed a good Hosmer-Lemeshow fit (χ
conclusionsVascular complications following total cerebral angiography by TRA in elderly CVA patients are associated with multiple factors. The nomogram model developed from these risk factors has significant predictive value.
