Absence of Severe Acute Respiratory Syndrome-Coronavirus-2 RNA in ocular tissues.
Article in American journal of ophthalmology case reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
purposeTo evaluate the status of ocular donor tissues of a COVID-19 postmortem donor.
methodsSARS-CoV-2 was detected via a pharyngeal swab and broncho-alveolar lavage in the COVID-19 suspect. Postmortem tissue procurement and preparation were performed with personal protective equipment (PPE) and the necessary protective measures. qRT-PCR-testing was performed for the following ocular tissues and fluids: conjunctival fluid swabs, bulbar conjunctiva, corneal epithelium, corneal stroma, corneal endothelium, anterior chamber fluid, lens, iris, vitreous, retina, uvea, sclera, and optic nerve. Informed consent and Institutional Review Board approval was obtained prior to this study (196/2020BO2; Date of approval: 03/26/2020; Ethics Committee of the University of Tuebingen).
resultsIn all ocular tissue and fluid samples no SARS-CoV-2 RNA was detected via qRT-PCR of the confirmed COVID-19 postmortem donor. CONCLUSIONS AND IMPORTANCE:
