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

purposeIdentify the factors associated with endothelial cell density in donor corneas.

methodsA cross-sectional analytical study of the records of 269 corneas procured between December 2016 and September 2021 in an eye bank of an ophthalmological institute in Colombia.

resultsThe median age of the 269 donors was 47 years (range: 18-72 years). A negative correlation was identified between donor age and endothelial cell density. On average, for each additional year of age, the median density decreased by 15.44 cells/mm

conclusionThe primary factor affecting the endothelial cell density of the corneas was the age of the donor. The data indicated a negative correlation with the presence of diabetes. Density levels differed depending on the procurement site and the individual responsible for the procedure.
