A Contemporary Risk Analysis of Iatrogenic Transmission of Creutzfeldt-Jakob Disease (CJD) via Corneal Transplantation in the United States.
Review in Ophthalmology and therapy, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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.
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
backgroundCreutzfeldt-Jakob disease (CJD) is a rare, fatal, neurodegenerative prion disease potentially transmissible through corneal transplantation. While statistical analyses performed two decades ago estimated the overall prevalence of CJD in the corneal donor pool to be low, the recent significant increase in corneal transplants performed and deaths due to CJD in the U.S. warrants a contemporary risk analysis.
methodsA literature review was conducted to determine the overall number of globally reported cases of CJD transmission through corneal transplantation. U.S. mortality and cornea donation data were utilized to estimate the age-stratified prevalence of undiagnosed, latent CJD in the cornea donor pool in 2018. A historical statistical analysis was performed to estimate the number of corneas from donors with latent CJD entering the U.S. donor pool for each year between 1979 and 2018. From these statistical analyses, risk factors of iatrogenic transmission were identified and summarized.
resultsTen reported cases of iatrogenic transmission of CJD through corneal transplants were identified globally. In 2018, an estimated 3.8 corneas from donors with undiagnosed latent CJD potentially entered the pool of 111,703 transplant-intended corneas harvested from individuals aged 31-80. Between 1979 and 2018, an estimated 47 corneas may have entered the U.S. transplant-intended pool from donors with latent CJD aged 35 to 84. The advanced age of donors and a history of multiple transplants in recipients were both prominent risk factors for iatrogenic transmission.
conclusionsThe 10 reported global cases of iatrogenic transmission likely under-represent the number of individuals with a coinciding history of death by CJD and prior corneal transplantation, as supported by our statistical analysis and lack of geographical diversity of reported cases. As effective screening methods develop and globalization of cornea transplantation broadens, it is of utmost importance that cornea transplantation history among victims of CJD should be investigated and reported.
