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

Objective: With the improvement of people's living standards, the demand for eye health is no longer limited to being visible, but more importantly, being able to see clearly. The aging population has led to increasing attention on presbyopia worldwide. Our study aims to reveal the prevalence and related factors of uncorrected presbyopia among urban and rural adults over 50 years of Fujian Province Southeast China. Methods: A population-based cross-sectional study was performed to evaluate the prevalence and related factors of presbyopia among urban and rural adults over 50 years in more than 50 communities of Fujian Province Southeast China from May 2018 to October 2019. A total of 8,211 residents aged over 50 years underwent a questionnaire and a series related examinations. Presenting near visual acuity (PNVA) was measured using logarithmic visual acuity chart at a distance of 40 cm, and uncorrected presbyopia was defined as PNVA worse than N6. Results: Among the 8,033 residents included in this study, the prevalence of uncorrected presbyopia was 68.6% ( Conclusions: There was a significant burden of uncorrected presbyopia in southeast China, which suggested more investment in accessible services and policy to enhance eye health especially on less educated and low income elderly with high IOP and refractive error. Although age is a significant correlate, its value in discriminating presbyopia in an individual is modest at best within this age-homogeneous population.
