Niin syytä en tiedä minkä takia kyseiset julkaisut eivät tuota tutkimusta halunneet julkaista. Lancet sen sijaan mm julkaisi täysin huuhaa "tutkimuksen" WHO:lta maskejen hyödyistäMeitsi70 kirjoitti:
Eli et osaa omin sanoin kertoa mitä siinä tutkittiin vai miksi kiertelet? Oletko lukenut ko. tutkimusta? Miksi mielestäsi esim. The Lancet, The New England Journal of Medicine ja the American Medical Association’s journal JAMA eivät julkaisseet tutkimusta?
Tuossa hieman lisää näitä Tanskalaisten tutkimusta tukevia tutkimuksia. Tanskalaisten tutkimus oli kattavin aiheesta tehty.

there is no evidence for the effectiveness of face masks and that the improper daily use of masks by the public may in fact lead to an increase in infections
Eli jos sulla on monta tutkimusta aiheesta, niin sitten väittämäsi on totta? Ei…tiede ei toimi noin. Tutkimusten laatu ratkaisee, ei mikään vyörytys.
