Multicentric Angiographic Assessment of the Branching Patterns and Anastomotic Network of the Genicular Arteries, with Implications for Genicular Artery Embolization.
Article in Cardiovascular and interventional radiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
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
purposeTo describe the anatomy of the genicular arteries and their anastomoses based on intraprocedural digital subtraction angiography (DSA). MATERIALS AND
methodsThis retrospective, multi-center study reviewed patients who underwent genicular artery embolization (GAE) between January 2019 and December 2023. DSA images were analyzed to assess the anatomy of the genicular arteries and their anastomoses.
resultsA total of 393 GAEs in 358 patients with minimal to severe knee osteoarthrosis (OA; Kellgren/Lawrence Grade I-IV) were analysed. Anastomoses between genicular branches were observed in all patients. In the medial compartment, anastomoses were identified between the descending genicular artery (DGA) and superior medial genicular artery (SMGA) in 158 GAEs (40%), the DGA and inferior medial genicular artery (IMGA) in 132 GAEs (34%), and the SMGA and IMGA in 64 GAEs (16%). In the lateral compartment, anastomoses were observed between the superior lateral genicular artery (SLGA) and inferior lateral genicular artery (ILGA) in 192 GAEs (49%), the ILGA and anterior tibial recurrent artery (ARTA) in 152 GAEs (39%), and between the SLGA, ILGA and ARTA in 91 GAEs (23%). Anastomoses between the medial and lateral compartments were identified between the DGA and SLGA in 59 GAEs (15%), the DGA and ILGA in 87 GAEs (22%), and the IMGA and ILGA in 94 GAEs (24%). The mean vessel diameter of the anastomoses ranged from 0.2 to 1.1 mm.
conclusionAnastomoses between genicular arteries are frequent and extensive, with diameters exceeding the sizes of particles (100-300 μm) and microcatheters (1.7-2.4F) commonly used in GAE.
