Are we in the COVID ward now?
Those goalposts are on a truck doing 90 mph!
And yes, until you have a pertinent risk assessment study, whatever you said is no more than opinion and conjecture.
But then again, since you affirm a study is "poorly designed and populated" simply because it yields statistically insignificant results (and lack of significance does not automatically imply results are "meaningless" -- especially if it happens in several studies), this conversation suddenly becomes even more pointless.
Ummm... yeah it does... take McIntyre for example. Does wearing a mask and washing your hands reduce you risk by 99% to just a 1% relative risk of infection? Or does it increase your risk 8-fold over not wearing a mask and washing your hands making you 8 time more likely to be infected than doing nothing?
The answer, according to McIntyre is probably (to a 95% degree of confidence) somewhere in that range. (see McIntyre in the table above from the meta-analysis under A for mask and hand-washing)
Also take the Aeillo 2012 study... It found that wearing a mask BUT NOT WASHING YOUR HANDS (part B of the table) was more protective than wearing a mask AND washing your hands (part A of the table).
So wear a mask, but what ever you do, don't wash your hands!!!
ETA: Or look at Barasheed - mask plus hand-washing is either 67% protective (RR = 0.33) OR 169 times (RR=169.47) more likely to get you infected! Lol!
On a new page, so here it is again:
