1 · What the graph read from 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.

2 · The registry

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 develop expert-consensus recommendations for patient selection, technique and clinical management in genicular artery embolization (GAE) using a Delphi process. MATERIALS AND

methodsA working group developed a 75-statement questionnaire. A panel of musculoskeletal and interventional radiologists (IRs), selected based on clinical experience, scientific expertise and geographic diversity, scored each response using a 10-point Likert-scale across three rounds. Consensus was predefined as ≥ 75% of ratings ≥ 7/10.

resultsTwenty-nine IRs completed all three rounds. Consensus inclusion criteria for GAE include knee pain refractory to conservative treatment for ≥ 3 months due to osteoarthritis, tendinopathies or prior knee surgery and recurrent hemarthrosis (median 9[IQR 7-10]; 86% ≥ 7). Pre-procedural assessment should include standardized outcome measures, clinical examination and knee radiographs. Contrast-enhanced MRI is optional for osteoarthritis phenotyping and grading of synovitis, differential diagnosis and outcome prediction (8[7-10]; 79% ≥ 7). Via an ipsilateral antegrade transfemoral access, all visible genicular arteries should be catheterized and embolized upon detection of a hypervascular blush (9[7-10]; 76% ≥ 7). No evidence of superiority of either temporary or permanent embolic agents in terms of safety or efficacy has been demonstrated (10[8-10]; 86% ≥ 7). Structured long-term follow-up is recommended, with clinical success defined as achievement of the minimal clinically important difference or individual patient satisfaction (9[7-10]; 83% ≥ 7). Contralateral or repeat GAE may be considered for bilateral knee pain, insufficient response or pain recurrence (8[7-10]; 76% ≥ 7).

conclusionThis Delphi study establishes expert-derived consensus recommendations for GAE, emphasizing broad indications, patient-tailored technique and an active role of the IR in multidisciplinary longitudinal care.
