Loss of follow-up after carotid revascularization is associated with worse long-term stroke and death.
Article in Journal of vascular surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesSociety for Vascular Surgery practice guidelines recommend surveillance with duplex ultrasound scanning at baseline (within 3 months from discharge), every 6 months for 2 years, and annually afterward following carotid endarterectomy or carotid artery stenting. There is a growing concern regarding the significance of postoperative follow-up after several vascular procedures. We sought to determine whether 1-year loss to follow-up (LTF) after carotid revascularization was associated with worse outcomes in the Vascular Quality Initiative (VQI) linked to Vascular Implant Surveillance and Interventional Outcomes Network (VISION) database.
methodsAll patients who underwent carotid revascularization in the VQI VISION database between 2003 and 2016 were included. LTF was defined as failure to complete 1-year follow-up in the VQI long-term follow-up dataset. Data about stroke and mortality were captured in the VISION dataset using a list of Current Procedural Terminology, International Classification of Diseases (Ninth Revision), and International Classification of Diseases (Tenth Revision) codes linked to index procedures in VQI. Kaplan-Meier life-table methods and Cox proportional hazard modeling were used to compare 5- and 10-year outcomes between patients with no LTF and those who were LTF.
resultsA total of 58,840 patients were available for analysis. The 1-year LTF rate was 43.8%. Patients who were LTF were older and more frequently symptomatic, with chronic obstructive pulmonary diseases, chronic kidney diseases, and congestive heart failure. Also, patients who underwent carotid artery stenting were more likely to be LTF compared with carotid endarterectomy patients (54.5% vs 42.3%; P < .001). The incidence of postoperative (30 days) stroke was higher in the LTF group (2.9% vs 1.7%; P < .001). Cox regression analysis revealed that LTF was associated with an increased risk of long-term stroke at 5 years (hazard ratio [HR]: 1.4, 95% confidence interval [CI]: 1.2-1.6; P < .001) and 10 years (HR: 1.3, 95% CI: 1.2-1.5; P < .001). It was also associated with significantly higher mortality at 5 years (HR: 2.5, 95% CI: 2.3-2.8; P < .001) and 10 years (HR: 2.2, 95% CI: 1.9-2.5; P < .001). Stroke or death was significantly worse in the LTF group at 5 years (HR: 2.3, 95% CI: 2.1-2.5; P < .001) and up to 10 years (HR: 2.02, 95% CI: 1.8-2.3; P < .001).
conclusionsOne-year follow-up after carotid revascularization procedures was found to be associated with better stroke- and mortality-free survival. Surgeons should emphasize the importance of follow-up to all patients who undergo carotid revascularization, especially those with multiple comorbidities and postoperative neurological complications.
