1 · What the graph read from 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.

2 · The registry

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

Purpose: To provide normative data on anterior segment parameters associated with glaucoma in a Ghanaian population and examine their associations with demographic and anthropometric variables. Patients and Methods: A total of 338 eyes from 116 males and 222 females (mean age: 61.86 ± 9.54 years, range: 45-89 years) were included in this cross-sectional observational study. Ocular examinations included visual acuity using Snellen chart at 6 m, auto-refraction using Retinomax K+ Screen Hand-Held Autorefractor, Goldmann applanation tonometry, slit-lamp biomicroscopy, fundus examination using 90D Volks lens and Pentacam tests using Oculus Pentacam Results: Mean values for corneal parameter measurements were: central corneal thickness (CCT) = 513.42 ± 34.63 µm, corneal diameter (CD) = 11.33 ± 0.44 mm, corneal volume (CV) = 58.14 ± 4.13 mm Conclusion: Thinner CCT and marginally lower CV in Ghanaians may be associated with glaucoma risk. Larger ACA, ACV and deep ACD may contribute to the relatively lower prevalence of angle-closure glaucoma reported in Ghanaians.
