Case Report: Persistent fetal vasculature associated with lenticular coloboma.
Article in Frontiers in medicine, 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
Background: Persistent fetal vasculature (PFV) is a rare congenital ocular anomaly, featuring typical fibrovascular stalks in the vitreous cavity. PFV may cause anterior and posterior segment anomalies such as leukocoria, microphthalmos, cataract, elongated ciliary processes, optic nerve hypoplasia, intralenticular hemorrhage, retinal dysplasia and strabismus. However, cases of PFV concurrent with lenticular coloboma are rarely reported. This report presents a rare case of anterior PFV associated with lenticular coloboma. Case presentation: A 23-year-old female presented with poor vision since childhood and deteriorated visual acuity in the right eye for 10 years. Dilated examination showed a localized central posterior subcapsular opacity in the lens, a fibrous stalk on the central posterior capsule extending to the vitreous cavity, elongated ciliary processes on the nasal area. Also a crescent-shaped lens defect and zonular defect was observed at the nasal equatorial region. Anterior segment optical coherence tomography (AS-OCT) examination provided a clear visualization of a band-shaped high reflectivity signal on the central posterior capsule, extending into the vitreous cavity. Lens coloboma along with zonular defect was also visualized by 3D reconstructed images of AS-OCT scan. The patient received an optimized surgery of cataract and anterior vitrectomy, during which a capsular tension ring implantation was made and an IOL was implanted into capsular bag in one surgery. Ethical approval for this observational retrospective study was waived by the Ethics Committee of our hospital and a written informed consent was obtained from the patient for publication of this case report and any accompanying images. Conclusion: This case represents a rare coexistence of PFV and lens coloboma. The report highlights the distinctive diagnostic value of AS-OCT in identifying anterior PFV and discusses the application of optimized surgical strategies in the management of this complex presentation.
