Aqueous Humor Liquid Biopsy to Exclude Retinoblastoma for a Child with an Intraocular Mass.
Article in Case reports in ophthalmology. 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
Introduction: Intraocular masses in children may present diagnostic dilemmas when clinical examination and imaging are insufficient to diagnose or exclude retinoblastoma. Furthermore, direct biopsy is contraindicated because of the risk of tumor seeding in retinoblastoma. Recent research has shown that aqueous humor biopsy is a safe method of obtaining cell-free DNA which can be used to diagnose retinoblastoma with high sensitivity and specificity, which provides a significant benefit in cases when the diagnosis is otherwise unclear. Case Presentation: An 11-month-old female presented with poor visual behavior since birth and an intraocular mass in the left eye. Examination under anesthesia revealed a detached retina rolled into a stalk attached to the optic nerve in the right eye and a white retrolental mass with perfused vessels in the left eye. Magnetic resonance imaging demonstrated a heterogeneous mass filling the left globe with diffusion restriction and contract enhancement. Aqueous humor liquid biopsy was performed in both eyes with low DNA yield and no mutations associated with retinoblastoma were identified. The patient was observed with no interval change in examination for 6 months. Conclusion: Aqueous humor liquid biopsy can be used to exclude a diagnosis of retinoblastoma in cases of pediatric intraocular mass with uncertain diagnosis.
