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

Purpose: To describe an observed peripheral corneal finding in a case of Ascher ring in a patient diagnosed with Sjögren's syndrome. Methods: Case report. Results: In this case, the Ascher ring appeared to demarcate the transition between the clear central cornea and the peripheral cornea, which exhibited observed deep stromal dotted and filiform opacities. Conclusions: After conducting a literature review on August 11, 2025, utilizing PubMed, Google Scholar, and Scopus with the keywords "Ascher ring," "corneal opacity," and "stromal ring," we did not find prior reports describing dotted and filiform peripheral deep stromal opacities associated with Ascher ring. These findings may represent an underrecognized manifestation of this entity. Given the concomitant diagnosis of Sjögren's syndrome, further investigation into possible associations between this corneal finding and autoimmune conditions is warranted.
