COVID-19 positivity rate in corneal tissue donors - A cause for concern!
Article in Indian journal of ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Purpose: To determine the postmortem positivity for COVID-19 among voluntary eye donors who had been certified to have died of non-COVID-19 causes. Methods: All donors who donated their corneas (from March 2021 onward) were assessed for COVID-19 positivity tested by nasopharyngeal swab reverse transcription-polymerase chain reaction (RT-PCR) test. Relevant screening history was taken prior to collection. Strict precautions were taken during the retrieval as per the guidelines issued by the National Program for Control of Blindness and Visual Impairment and the Eye Bank Association of India, and the tissues were handled as per standard operating protocol. Results: 85 eye calls were attended during this period, of which 56 were home-based and 29 were from a hospital setting. Samples from 12 of the former group of donors were found to be positive for COVID-19 (14%). Conclusion: This study highlights the possibility of postmortem RT-PCR positivity in voluntary corneal tissue donors without a prior history of symptoms, signs, or diagnosis of illness suggestive of COVID-19. It is recommended that postmortem testing of donors should be done by RT-PCR for retrievals made during the pandemic.
