Crude and standardized prevalences of cataract and related factors in the elderly people in Northern Iran.

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
purposeThis study aims to estimate the crude and standardized prevalences of cataract and its related factors among old people in northern parts of Iran.
methodsThis cross-sectional study was carried out among 397 people aged 60 and older in northern Iran. Required information about treated and nontreated cataract was collected using a standard checklist. The World Standard Population was applied for direct standardization.
resultsThe standardized prevalence (95% confidence interval) of cataract among men, women, and all people were 27.5% (21.2-33.8), 30.9% (24.5-37.4), and 29.1% (24.6-33.6), respectively. Based on multivariate logistic regression models, age over 75 years (OR = 3.03, 95% CI: 1.21-7.59), living alone (OR = 4.89, 95% CI: 1.86‒12.86), diabetes mellitus (odds ratio = 19.10, 95% confidence interval: 8.13-44.89), rheumatoid arthritis (OR = 7.76, 95% CI: 2.32-25.99), history of infectious diseases (OR = 4.02, 95% CI: 1.35‒11.98), hypertension (OR = 3.19, 95% CI: 1.59-6.42), history of ophthalmic surgery (OR = 2.83, 95% CI: 1.29-6.16), history of sedative drug use (OR = 2.71, 95% CI: 1.35-5.47), history of vitamin supplementation use (OR = 0.21, 95% CI: 0.08-0.55), and familial history of cataract (OR = 2.81, 95% confidence interval: 1.38-5.72) increased the odds of cataract. Our multiple logistic regression model explained 53% of the variation in developing cataract.
conclusionOur study showed that the prevalence of cataract in the study population was relatively high. We also found that aging, living alone, diabetes mellitus, rheumatoid arthritis, hypertension, infectious diseases, ophthalmic surgery, sedative drugs and familial history of cataract were the risk factors of cataract and vitamin supplementations were its protective factors.
