Individual patient data meta-analysis of patients treated with a heparin-bonded Viabahn in the femoropopliteal artery for chronic limb-threatening ischemia.

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
objectivesThe aim of the study was to analyze available data on patients treated for chronic limb-threatening ischemia (CLTI) with the heparin-bonded Viabahn endoprosthesis.
backgroundThe patency of self-expanding covered stents in patients with complex femoropopliteal lesions is encouraging. However, data were mostly derived in patients with intermittent claudication. Patients with CLTI often have more advanced disease and worse outcome.
methodsAfter the abstract screening, full-text papers were checked. Authors were approached to consider joining the consortium. Data were sent anonymously, databases were merged and an individual patient data meta-analysis was performed. Kaplan-Meier curves were used to calculate the freedom from amputations, the amputation-free survival, and patency rates.
resultsSeven studies were enrolled, representing 161 limbs that were treated for CLTI. Median lesion length was 28.0 cm (interquartile range 25.0-33.0 cm) and 82.7% were chronic total occlusions. The technical success rate was 98.1% and the 30-day mortality 1.9%. Through 2-year follow-up, the freedom-from-major-amputations was 99.3%, with an amputation-free survival of 78.8%. The freedom-from-loss-of primary, primary-assisted, and secondary patency was 70.4%, 71.8%, and 88.2%, respectively, at 1-year and 59.5%, 62.7%, and 86.1% at 2-year follow-up, respectively. The reintervention-free survival was 62.2% at a 2-year follow-up.
conclusionsTreatment of femoropopliteal disease in CLTI patients with the use of the heparin-bonded Viabahn is safe and effective with favorable clinical outcomes and low amputation rates. Reinterventions are needed in a subset of the population to maintain endoprosthesis patency. Close follow-up using duplex is recommended to detect potential edge stenosis, allowing treatment before device occlusion.
