Targeted Transvenous Embolization Under Sinus Balloon Protection for Transverse-Sigmoid Sinus Dural Arteriovenous Fistula: A Technical Note.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Dural arteriovenous fistulas (DAVFs) at the transverse-sigmoid sinus (TSS) are often treated with transarterial embolization (TAE) or sinus occlusion. Although sinus balloon protection has become increasingly utilized in TAE to preserve sinus patency, its application in transvenous embolization (TVE) has rarely been reported. In a case involving a Borden type Ⅰ/Cognard IIa TSS DAVF with localized parasinus shunting, three-dimensional rotational angiography clearly delineated the detailed structure of the shunted pouch, allowing precise transvenous access. TVE was successfully performed using coils and Onyx under sinus balloon protection, resulting in complete occlusion of DAVF while maintaining sinus patency. Targeted TVE under sinus balloon protection may offer a viable, sinus-preserving alternative to conventional TAE or sinus occlusion in select cases of TSS DAVFs with parasinus shunt concentrations.
