Antioxidant Support for the Corneal Endothelium: Evidence from Vitamin C Supplementation in Hard Cataract Phacoemulsification.
Article in F1000Research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06781970 (The Effects of Vitamin C Supplementation on Corneal Endothelial Damage in Hard Cataract Phacoemulsification), which is not on this 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.

Abstract
Background: Phacoemulsification is one of the most frequent surgeries in the world. However, prolonged use of phacoemulsification machines produces reactive oxygen species which will damage corneal endothelial cells. Ascorbic acid has an antioxidant capacity to neutralize oxidative stress in the anterior chamber. This study will investigate the protective effect of ascorbic acid on corneal endothelial cells in patients with hard nuclear cataracts. Methods: This study is a double-blinded randomized controlled trial. Samples will be divided into three groups, and 500 mg vitamin C three times daily (1500 mg/day), or placebo will be received for seven weeks. Clinical characteristics, ascorbic acid, malondialdehyde, and total antioxidant capacity of patients in serum and aqueous humor will be measured before and after intervention and phacoemulsification. Conclusions: Data from this study will reveal the protective effect of oral vitamin C supplementation on the corneal endothelial cells in patients with hard nucleus cataracts.This trial has been registered at ClinicalTrials.gov (identifier: NCT06781970; registered on 17 January 2025).
