Effect of 2% Hyaluronic Acid on the Rate of Healing of Corneal Epithelial Defect After Pterygium Surgery: A Randomized Controlled Trial.
Trial report in Drug design, development and therapy, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
purposeThe study aimed to investigate the effects of 2% hyaluronic acid (HA) on corneal epithelial defect after pterygium surgery in comparison with the control group, measured in terms of the healing rate of corneal epithelial defect and pain score after surgery.
methodsIn this double-blind randomized clinical trial, fifty patients with primary pterygium were randomized into 2 groups: a control group or the group treated with a single topical application of 2% HA. Comprehensive ophthalmological examinations included measuring the area of corneal epithelium defect using ImageJ freeware and the pain score assessment after the operation.
resultsThe mean and SD of the area of epithelial defect measured on postoperative Day 0, 1, and 2 were 10.89 ± 1.33 mm
conclusionA single topical application of 2% HA tended to accelerate the healing process of corneal epithelium defect after pterygium surgery without any observable adverse effects during short-term follow-up.
