Effectiveness of a Preschool Vision Screening Program for Early Detection of Refractive Errors: Evidence From a Prospective Study in Uzbekistan.
Article in AJPM focus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Evidence on the real-world performance of preschool vision screening remains limited in middle-income settings. This study evaluated a preschool-based vision screening program in Tashkent, focusing on coverage, diagnostic yield, referral completion, and selected contextual factors. Methods: A prospective evaluation was conducted from January 2025 to January 2026 in 24 state preschools across all 12 districts of Tashkent. Children aged 5-7 years underwent monocular visual acuity testing and noncycloplegic autorefraction. Screening outcomes were based on visual acuity in the worse eye; children with borderline (Vis=0.8-0.9) or reduced (Vis<0.8) visual acuity were classified as screen positive and referred for an ophthalmologic examination. Refractive assessment followed standard international definitions. Confirmatory examinations included objective refraction, with cycloplegic refraction used to confirm refractive error. Parental questionnaires and classroom illumination were analyzed descriptively. Results: Among 1,284 screened children (mean age of 6.39±0.58 years), 25.9% were screen positive, and 90.4% completed referral. Confirmed refractive errors were identified in 13.7%, most commonly hyperopia (38.6%). Limited prior eye care was observed despite generally positive parental attitudes, and most classrooms had suboptimal illumination. Conclusions: Preschool vision screening was feasible and yielded substantial case detection under routine urban conditions, supporting its integration into preschool health services.
