Masks have an effect on individual morbidity (not mortality).
Masks have no effect on the population morbidity (or very slight effect here) and zero, zip, nodda on mortality.
The general idea is that masks can reduce the infectious dose received, which in response to a healthy (generally non-susceptible) individual will reduce the disease severity. HOWEVER, in a susceptible individual, the reduction in dose has no effect; i.e. if you would have died from it you would die if you were infected with 100 or 10,000 infectious units. This is why masks work in health care settings to protect doctors, who could receive unusually high infectious doses from their patients, and if a non-susceptible person receives a high enough dose it can kill them (pretty much only applicable to health care settings).
Masks also reduce the infectious doses others would receive if you are sick, and if you are symptomatic and ill but need to go out then one should always wear a mask. But the idea of universal masking is just dumb, and has zero effect on population mortality rates and only the possibility of a slight reduction in disease severity from people who would not die from the disease. It will be interesting to see the spike in klebsiella / staph pneumonia for this year from people wearing masks too long.
NO statistical difference, better keep wearing masks. It's not the virus, it's about control.
So Im a microbiologist fag and I would like to try to explain why masks work, and don't work the way they using them.
If you do a search of the literature before the kung-flu you will see that all the studies show similar results (https://pubmed.ncbi.nlm.nih.gov/?term=face+mask+epidemiology&filter=years.1970-2019).
