Histopathologic findings of the lens capsule and persistent hyperplastic primary vitreous in Korean pediatric cataract patients.
Article in Scientific reports, 2024. 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
This study aimed to measure lens capsule thickness and investigate histopathologic characteristics of persistent hyperplastic primary vitreous (PHPV) in Korean pediatric cataracts. We analyzed lens capsules from 116 eyes of 83 pediatric cataract patients treated between 2011 and 2015. The mean thickness of the anterior/posterior capsule was 7.21 ± 1.74/4.39 ± 1.41 μm. PHPV was observed in 11.2% (13/116) of eyes. Histologic examination revealed that PHPV is typically characterized by retrolenticular membranes with hypercellular membrane tissue comprising vascular structures and/or mesenchymal cells, seen in 69% of cases. Only 3 patients had hyaloid arteries and endothelium-lined blood vessels in the retrolenticular membranes, whereas six eyes showed only mesenchymal cells. Lens capsule thickness did not significantly vary with age or the presence of PHPV in Korean pediatric cataracts. The primary histological characteristic of PHPV was the presence of mesenchymal cells, with or without vascular structures, supporting the role of endothelial-mesenchymal transition as a key mechanism in vascular regression.
