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
BACKGROUND/
objectiveTo report the prevalence, causes and risk factors of vision impairment (VI) among those aged ≥40 years in Nagar Kurnool district in Telangana, India. In addition, temporal trends in the prevalence of VI from various population-based studies conducted in this region are reported.
methodsThree study teams conducted eye examinations in the selected clusters at participants' households. Detailed eye examination, including visual acuity assessments were done. VI was defined as the presenting visual acuity worse than 6/12 in the better eye. Multiple logistic regression analysis is conducted to assess the factors associated with VI. The prevalence of VI from three population-based studies conducted over the last two decades in the same region were compared.
resultsA total of 2570/3000 (85.7%) were examined. Among those, 55.6% were women, and 22.1% had formal education. The prevalence of VI was 22.68% (95% CI:21.08-24.35). The odds for VI increased with increasing age. The participants with no formal education had higher odds for VI compared to those with formal education (OR: 2.25; 95% CI:1.66-3.06). The prevalence of VI declined from 49.9% in 1998 to 22.2% in 2014 and then to 20.8% in 2023.
conclusionVI is common in the state of Telangana. Given the aging in India, the stable VI in the last decade is a positive sign and suggests that eye care services have evolved to address the eye care needs of the people. However, more efforts are needed to reduce VI in the region.
