A Population-based Study of the Prevalence of Cataract and Its Relationship with Smoking in the Northwest of Iran: The Azar Cohort Eye Study.

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 purpose of the to determine the prevalence of cataract and study the relationship of smoking and other potential risk factors with visually significant cataract.
methodsThis is a cross-sectional study based on the Azar cohort databases including 11,208 participants aged 35-70 years of the general population. According to the questionnaire, participants were divided into five groups in terms of smoking. Eye examinations were performed in two steps. The first step was performed by an optometrist, and in the second step, participants with poor red reflex or visual acuity of <8/10 were examined by an ophthalmologist for diagnosing cataract.
resultsOf the participants, 4992 (44.5%) were male and 6216 (55.5%) were female, with a mean age of 50.1 ± 9.27 years. The prevalence of visually significant cataract was 7.2%. The frequency of ex-smoking in the male and female population in the cataract group was significantly higher than that in the noncataract group (male:
conclusionThere is no association between cigarette smoking in different doses and the history of smoking with cataracts but other factors such as aging, education level, and underlying diseases including diabetes mellitus, hypertension, and myopia have statistically significant association with visually significant cataract.
