Prevalence of dry eye in Brazil: Home survey reveals differences in urban and rural regions.
Article in Clinics (Sao Paulo, Brazil), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeA random home visit search investigated the prevalence and predictors of Dry Eye (DE) symptoms in Brazil.
methodsThrough home visits to 420 urban and 180 rural residences in the countryside of Southeast Brazil, the Dry Eye Disease Short Questionnaire (DEDSQ) was applied to volunteers 40 years and older. The predictive value of the DEDSQ and the risk factors were investigated.
resultsDE is more frequent in the urban population (38.1 % vs. 20 %; p < 0.0001) and was higher in females (37.5 % and 21.5 %; p < 0.0001). In the urban area, DE is associated with dyslipidemia (p < 0.0001), visual display terminal use > 2 h/day (p < 0.0001), and pterygium (p < 0.001), and in the rural area with dyslipidemia (p < 0.01) and prior ocular surgery (p < 0.05). In women, the predictors are antiallergics, chronic pelvic pain, fibromyalgia, and visual display terminal use > 2h/day. Aging was associated with distinct risk factors. DEDSQ showed 78.5 % of sensitivity and 71.1 % specificity.
conclusionThis first domiciliary study in Brazil reveals that DE symptoms were more prevalent in the urban area and among women. DE has distinct risk factors and a high prevalence in Brazil.
