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

backgroundTo identify factors associated with early age-related macular degeneration (AMD) in a rural Chinese population, with emphasis on retinal vessel caliber.

methodsThe study population comprised the 6,830 participants of the Handan Eye Study. All participants underwent digital retinal photography of both eyes. Trained graders assessed the presence of AMD lesions. Arteriolar and venular diameters were measured with a specific computer-assisted program and were summarized as the central retinal arteriolar equivalent (CRAE) and central retinal venular equivalent (CRVE).

resultsThe data for the 199 individuals with evaluable retinal photographs and early AMD and 400 age-matched individuals randomly selected from the group without AMD were analyzed. After adjusting for participants' age, sex, smoking status, hypertension, diabetes, BMI, and CRVE, the multivariate adjusted model showed that a higher CRAE was significantly associated with early AMD (OR = 1.34; 95% CI: 1.05-1.71; p = 0.020) and the presence of soft distinct drusen (OR = 1.32 (95% CI: 1.02-1.71, p = 0.037). There were no significant associations between CRVE and early AMD.

conclusionsDilated retinal arteriolar caliber is associated with early AMD and soft distinct drusen in this population. We found no significant associations between CRAE and other characteristics of the retina related to AMD or between retinal venal caliber and early AMD. More research is needed to determine whether the difference between these results and those previously published stem from the rural living conditions of the participants or other factors.
