It reveals that certain aspects of national lockdowns might have been more impactful than others. The researchers found, for example, that banning gatherings of more than 10 people or closing schools and universities was especially effective, reducing transmission by more than 35% on average. Shutting restaurants and bars seemed to make slightly less difference to transmission, however. What's more, the researchers suggest that adding a strict stay-at-home order on top of such measures "only had a small additional effect" in terms of slowing down Covid-19 – estimated at below 17.5% on average."
