As I read it, that is NOT what that article says. Some extracts:
And rather than focusing on a single measure, the authors conclude that a more comprehensive response is what is really effective:

"The emerging picture reveals that no one-size-fits-all solution exists, and no single NPI can decrease Rt below one. Instead, in the absence of a vaccine or efficient antiviral medication, a resurgence of COVID-19 cases can be stopped only by a suitable combination of NPIs, each tailored to the specific country and its epidemic age. These measures must be enacted in the optimal combination and sequence to be maximally effective against the spread of SARS-CoV-2 and thereby enable more rapid reopening."

You really ought to read and understand the article before citing it.

Thank you, Rich, for posting this extract.
The virus knows no politics. Everyone, including scientists, were ignorant of its biology, best anti-infective measures, and best treatment a year ago. Facts, through research, have been steadily accumulating. Sadly, opinions are often strongly held, even by "authorities", that are dissonant with fact. The discipline of practicing clinical medicine is that one quickly learns that using opinion instead of fact to treat patients is a disaster for the patient, which makes us cautious. Most people are not faced continually with this potentially catastrophic error-checking by nature, so opinions float free.

Dan, you might consider commenting about the actual data which showed that wearing PPE had little to no effectiveness. BTW, you are also welcome.
