Polymorphous corneal dystrophy subtype 3 and keratoconus aggravation after corneal refractive surgery in a three-generation family carrying both
Article in Frontiers in genetics, 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
Background: This study reports a three-generation Chinese family with polymorphous corneal dystrophy subtype 3 (PPCD3) and keratoconus (KC) aggravation induced by corneal refractive surgery, specifically small incision lenticule extraction (SMILE), in the context of genetic variations. Methods: The history of illnesses and blood samples of all family members were collected. One hundred healthy individuals served as normal controls. We conducted whole exome sequencing on genomic DNA and sanger sequencing to verify the variants between all controls and family members. Results: Three family members were previously diagnosed with subclinical keratoconus (III1 and III2 preoperatively, and II2). Both the proband (III1) and her younger brother (III2) underwent SMILE to correct refractive errors. One year later, visual acuity of III1 decreased significantly with KC aggravation and corneal opacification. The KC of III2 progressed significantly 6 months after surgery. Both were subsequently diagnosed with PPCD3. We detected both Zinc finger E-box-binding homeobox 1 (ZEB1) gene and zinc finger protein 469 (ZNF469) gene pathogenic variant in the proband and another two patients in this family, including a heterozygous missense variation c.13C>G (p.P5A, rs753301298) in the Conclusion: This study demonstrated the importance of a thorough ocular examination, especially the cornea, and a gene screening before SMILE.
