Prevalence of pterygium and pinguecula and their risk factors: Tehran Geriatric Eye Study.
Article in International journal of ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
aimTo explore the prevalence of pterygium and pinguecula and their risk factors.
methodsThis population-based cross-sectional study was conducted on geriatric population aged 60 and over in Tehran, Iran from Jan 2019 to Jan 2020. Selected subjects were interviewed and subjected to optometric and ophthalmic examinations.
resultsThe age and sex standardized prevalence of pterygium and pinguecula was 3.64% [95% confidence interval (CI): 2.94%-4.49%] and 55.57% (95%CI: 52.89%-58.22%), respectively. The prevalence of pterygium was 4.52% (95%CI: 3.5%-5.81%) in men and 2.79% (95%CI: 1.97%-3.94%) in women and the prevalence of pinguecula was 64.56% (95%CI: 60.92%-68.03%) in men and 46.72% (95%CI: 43.74%-49.72%) in women. According to the results of multiple logistic regression, pinguecula had a significant correlation with male sex [odds ratio (OR): 2.21, 95%CI: 1.63-2.99] and education level (OR: 0.52, 95%CI: 0.35-0.77) and pterygium had a significant relationship with male sex (OR: 2.2, 95%CI: 1.38-3.52), socioeconomic status (SES, OR: 0.5, 95%CI: 0.26-0.97), education level (OR: 0.22, 95%CI: 0.08-0.61).
conclusionThe prevalence of pinguecula and pterygium in this study are lower than other studies. Sex, SES, and education level are the risk factors of the prevalence of pinguecula and pterygium.
