1 · What the graph read from it

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.

2 · The registry

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: Presbyopia is a major cause for near visual impairment among adults. Presbyopia induced visual impairment can be corrected easily by spectacles. We aimed to study the prevalence of presbyopia among adults aged ≥35 years and spectacles coverage among them. We also studied the unmet need for presbyopia along with the barriers to uptake of services. Methods: This is a population-based cross-sectional study conducted among adults aged ≥35 years in a rural district of Haryana. Near vision assessment and semistructured interview schedule were administered by a team of trained ophthalmic assistant, social worker and health assistant. Results: A total of 3832 adults aged ≥35 years were enumerated, from which 3246 (84.7%) were examined. Prevalence of presbyopia was found to be 42.9% (95% confidence interval 41.2-44.6). Participants with increasing age, literacy and women had higher prevalence, and those that were employed and belonged to below poverty line economic status had lower prevalence of presbyopia. Spectacles coverage among presbyopes was found to be 25.8%. There was an inverse association between unmet need for presbyopia and women, increasing education status and office work. Lack of felt need and personal reasons were the most common barriers for unmet need due to presbyopia. Conclusions: There is high prevalence of presbyopia among adult population, with spectacles coverage being low. Awareness activities along with affordable, accessible and socially acceptable services for those affected with presbyopia would be one of the key components of management.
