Nasal lavage containing Angiotensin-Converting Enzyme-2 agonist can prevent and reduce viral load in COVID-19.
Article in Medical hypotheses, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
COVID-19 has been the talk of the year 2020, taking many lives and leaving others in critical conditions. It has clearly and severally been reported that the SARSCoV-2 uses the Angiotensin Converting Enzyme-2 receptors to penetrate and infect cells. Reports have also stated that the nasal and olfactory mucosa are overloaded with these receptors. We emphasize that anosmia in COVID-19 is secondary to the binding of the SARSCoV-2 to Angiotensin Converting Enzyme-2 receptors on the olfactory mucosa. A hypotheses pertaining to the presentation, diagnosis, management and possible prevention of SARS-CoV-2 is proposed. Given the high false negative rates of the polymerase chain reaction (PCR) tests, we suggest that COVID-19 negative patients with anosmia without any other nasal symptom should raise a high index of suspicion and should be further evaluated. We propose the formulation and use of Angiotensin Converting Enzyme-2 receptors agonist or angiotensin receptor blockers (ARBs) as nasal lavage, to reduce the viral load of confirmed positive patients, and as a mode of prevention, especially in high risk patients, until a vaccine is developed. These medications are readily available and testing this theory involves determination of the correct dosage of angiotensin receptor blockers or ACE inhibitors (via dilution in water) that can be used as nasal lavage and performing efficacy trials. Potential side effects to be monitored for include low blood pressure or changes in heart rate. Administration of a medicated nasal lavage may be easier and rapidly disseminated on the nasal mucosa.
