RCT 524 outpatients in the USA for a nitric oxide generating lozenge, showing no significant difference in combined hospitalization, ICU admission, intubation, dialysis, and death. There were only 3 events in each arm, all occuring in 2020, with zero events in 2021 or 2022. Recovery was 11% faster with treatment, without statistical significance. Authors note that a higher dose may have been more effective. Trials showing greater efficacy have used a nasal spray.
risk of progression, 0.8% higher, RR 1.01, p = 1.00, treatment 3 of 261 (1.1%), control 3 of 263 (1.1%), combined hospitalization, ICU admission, intubation, dialysis, and death.
recovery time, 11.2% lower, relative time 0.89, p = 0.30, treatment 261, control 263.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.
