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: This study aimed to assess the feasibility, safety, and clinical performance of retrograde pedal access to facilitate intraluminal crossing in complex infrainguinal chronic total occlusions in patients with advanced peripheral artery disease. Methods: In this retrospective, single-centre analysis, 33 patients undergoing endovascular revascularization for complex peripheral arterial chronic total occlusions between August 2021 and October 2024 were evaluated. Retrograde pedal access was performed when intraluminal crossing could not be achieved using antegrade or contralateral femoral approaches. The primary endpoint was technical success, defined as successful intraluminal crossing. Secondary endpoints included procedural complications, freedom from clinically driven target lesion revascularisation, longitudinal changes in Rutherford classification, wound healing, limb salvage and all-cause mortality. Results: Successful intraluminal crossing via retrograde pedal access was achieved in 30 patients (90.9%). The posterior tibial artery (39.4%) and anterior tibial artery (36.4%) were the most commonly utilized access sites. Among the 30 patients who underwent definitive endovascular treatment after successful intraluminal crossing, the most frequent complication was flow-limiting dissection, occurring in five patients (16.7%); no cases of perforation, distal embolization, pseudoaneurysm, arteriovenous fistula, or procedure-related death were recorded. Kaplan-Meier estimated freedom from clinically driven target lesion revascularization was 96.7% at 12 months and 75.5% at 24 months. No major amputations occurred, and all patients presenting with tissue loss achieved complete wound healing, with or without minor amputation. Conclusion: Retrograde pedal access represents a safe and effective approach for achieving intraluminal crossing in complex peripheral chronic total occlusions, particularly among patients with chronic limb-threatening ischemia. The high rate of technical success and favorable limb-related outcomes support its role as an integral component of modern endovascular revascularization strategies.
