The Study
Broad-Spectrum Virucidal Activity of Nitric Oxide Nasal Spray (NONS) Against SARS-CoV-2 Variants and Major Respiratory Viruses
This is like testing if a cleaning spray kills germs in a petri dish. It shows the spray can kill viruses in a lab, but we don't know if it would work the same way in people's noses or prevent sickness.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
A nose spray with nitric oxide quickly kills many cold and flu viruses in lab tests.

This says that a substance called NONS can quickly kill certain viruses that cause respiratory infections, making them almost completely harmless in lab tests.
A substance called NONS quickly kills flu viruses in a lab setting, making them almost completely gone in just a few seconds.
A substance called NONS can kill many different types of viruses in lab tests, and it works by using nitric oxide to change the virus's proteins, which stops them from working.
A nose spray with nitric oxide quickly kills over 99.9% of the COVID-19 virus and its variants in lab tests, working in as little as 30 seconds.
NONS is a disinfectant that quickly kills over 99.97% of a tough cold virus in a lab test, while regular alcohol only killed about 37% of the virus.
A nose spray with nitric oxide can quickly kill over 99% of flu, COVID, and cold viruses in lab tests.
