Feasibility of percutaneous coronary intervention using a 7-French thin-walled sheath via the distal radial access.
Observational study in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05006027 (Feasibility of Percutaneous Coronary Intervention Using a 7-Fr Thin Walled Sheath Via the Distal Radial Approach), which is not on this map. Cited by 2 papers.
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

Abstract
We evaluated the feasibility and safety of the 7-Fr hydrophilic coated thin-walled sheath for distal radial access (DRA) - percutaneous coronary intervention (PCI). We prospectively collected data from 100 patients who underwent PCI via DRA with a 7-Fr hydrophilic thin-walled sheath at a single center in Korea between August 2021 and April 2024. Co-primary outcomes were PCI success rate and access site complications assessed by vascular ultrasound during hospitalization and at 1-month follow up. The mean age of study population was 65.9 years, and all patients presented acute coronary syndrome. DRA-PCI was successful in all patients. Of the 43 patients evaluated forearm radial artery with intravascular imaging after PCI, there were 2 cases of thrombus and 1 intimal dissection. Access site complications included 2 small hematomas and 1 hand edema. Vascular ultrasound performed the day after PCI showed no forearm radial artery occlusion (RAO) but 2 distal RAO cases without serious complications. At 1 month follow-up, 2 consistent and 1 new case of distal RAO were observed without hand dysfunction. The SEVEN-BOX trial showed that DRA using a 7-Fr hydrophilic coated thin-walled sheath could be a feasible and safe option for complex PCI.Clinical trial registration: https://www.clinicaltrials.gov .
