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

backgroundVenous vascular malformations (VVMs) are congenital vascular anomalies, often impacting quality of life due to discomfort, swelling, and functional impairments. This study evaluates the efficacy of bleomycin sclerotherapy as a treatment for symptomatic VVMs of the tongue.

methodsWe conducted a retrospective review of all patients treated with this method in our institution between 2004 and 2024. Sclerotherapy procedures were performed under general anesthesia in the neuroangiography suite with fluoroscopic guidance using a negative subtraction technique. Outcomes were assessed through subjective patient reports and magnetic resonance imaging (MRI) where available.

resultsIn total, 140 percutaneous bleomycin sclerotherapy procedures were performed on 36 patients (aged 19-80) with tongue VVMs. On average, patients required 2.06±1.8 treatment sessions and 2.29±1.4 procedures per session. The average interval between treatment sessions was 28.6±19.4 months. Per procedure, the total units of bleomycin injected was 11.2±3.9 mg/mL (2-15 mg/mL). Results revealed that 93.8% of procedures yielded subjective symptom improvement. Follow-up imaging was available in 14 patients and confirmed lesion reduction in nine (64.3%). Post-procedural complications were minimal, with transient swelling as the most common.

conclusionPercutaneous bleomycin sclerotherapy presents an effective, well-tolerated treatment for tongue VVMs, offering significant symptom relief. To our knowledge, this study represents the largest retrospective series of bleomycin sclerotherapy for tongue VVMs to date. Our findings support bleomycin sclerotherapy as a valuable option for managing VVMs in this challenging anatomical site.
