Risk prediction for adverse events after carotid artery stenting in higher surgical risk patients.
Article in Stroke, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 19 papers, 1 of them a synthesis that pooled it.
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
background and purposeThe goal of carotid artery stenting is to decrease the risk of stroke or other adverse events from carotid artery disease. Choosing a treatment strategy requires patient-specific information regarding periprocedural risk of adverse neurologic events. The aim of this study was to predict individual patient risk after carotid artery stenting in patients at higher risk for carotid endarterectomy.
methodsSubjects enrolled in the Stenting and Angioplasty with Protection in Patients at High-Risk for Endarterectomy (SAPPHIRE) worldwide study underwent carotid artery stenting with distal protection. Only patients with at least 1 anatomic or comorbid factor associated with elevated surgical risk were included. Preprocedural factors were used to develop a model and integer-based risk score predicting stroke or death within 30 days. The model was calibrated and internally validated using bootstrap resampling.
resultsTen thousand one hundred eighty-six patients were included in the analysis. The overall rate of stroke or death was 3.6% at 30 days after carotid artery stenting. Independent predictors of adverse outcomes were increased age (P=0.006), history of stroke (P<0.001), history of transient ischemic attack presentation (P=0.001), recent (<4 weeks) myocardial infarction (P=0.006), dialysis treatment (P=0.007), need for cardiac surgery in addition to carotid revascularization (P=0.005), a right-sided carotid stenosis (P=0.006), a longer carotid plaque (P=0.012), the presence of a Type II or III aortic arch (P=0.035), and a tortuous carotid arterial system (P=0.004). The optimism-adjusted C-statistic was 0.691.
conclusionsCommonly collected clinical and anatomic variables can identify patients at high and low risk for stroke or death after carotid artery stenting.
