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

backgroundKeratoconus is a complex disease of the cornea, in part caused by environmental exposures whose nature is not fully understood.

methodsThis study relied on previously published results from genome-wide association studies of European ancestry. Summary statistics of available genome-wide association studies on atopy, chronic inflammatory disease and serum glucose levels; results were paired with genomic association results for keratoconus into a well-powered and hypothesis-driven Mendelian Randomisation to statistically test the causal role that may have over keratoconus risk.

resultsOur results confirm a higher risk of keratoconus in patients having any atopic disease (OR = 1.84, 95%CI = 1.52-2.22), but also other chronic inflammatory conditions such as rheumatoid arthritis (OR
