Influence of Refractive Status, Residential Climate, and Adverse Environmental Factors in Contact Lens Dropout: Insights from a Survey-Based 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
introductionThis study aimed to analyze the influence of refractive status, residential climate, and exposure to adverse environmental factors in contact lens (CL) dropout.
methodsThis cross-sectional study involved a face-to-face survey conducted by trained optometrists among former and current CL wearers (CLWs) at General Óptica centers throughout Spain. The survey included questions related to demographic characteristics, refractive status, residential climate, and adverse environmental factors. The chi-square test and a forward stepwise binary logistic regression analysis were performed.
resultsA total of 1094 surveys were included, comprising 509 former CLWs and 585 current CLWs. Age (B = 0.03; OR 1.03, 95% CI 1.02-1.04) and exposure to chemical (B = 3.51; OR 41.67, 95% CI 12.06-143.95) or dusty environments (B = 1.05; OR 2.93, 95% CI 1.16-7.41) were significantly associated with CL dropout. However, residing in a continental climate was associated with a lower CL dropout compared with a Mediterranean climate (B = - 1.39; OR 0.25, 95% CI 0.15-0.42). Spherical refraction, cylindrical refraction, and near addition power did not show statistically significant associations with CL dropout. Furthermore, the model excluded sex, exposure to high-humidity or dry environments, and the interactions between adverse environmental factors and residential climate as predictive factors.
conclusionsOlder age, residence in the Mediterranean climate, and exposure to chemical or dusty environments increase the risk of contact lens dropout. However, climate-specific conditions do not appear to significantly influence dropout rates, suggesting that other factors may play a more important role.
