Xenogeneic Collagen-Based Dural Substitute, A Stranger in Sinonasal Pathology.
Article in Head and neck pathology, 2026. 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
Sinonasal mesenchymal neoplasms are challenging to classify due to their rarity. Xenogeneic collagen-based dural substitutes, such as DuraMatrix, are used for dural repair in sinonasal surgery, but their histologic features have been described only briefly in a few animal studies. When encountered in sinonasal specimens in the absence of a relevant surgical history, these materials may be mistaken for incidental mesenchymal neoplasms because of features such as intermixed spindle cells and a minimal foreign-body giant cell reaction. By detailing the histopathologic findings, we aim to facilitate recognition of dural substitutes among pathologists and avoid unnecessary diagnostic workup.
