This blog post concludes with an overlayed population-adjusted graph of the Covid death numbers for Sweden and Massachusetts: https://blogs.umass.edu/covidbalance/2021/01/02/why-is-sweden-a-bogeyman/ https://blogs.umass.edu/covidbalance/2021/01/02/why-is-swede... You are right that Massachusetts had the highest daily number of deaths in April, before the mask mandate was issued. Sweden peaked a couple weeks earlier than Massachusetts, with a max rate about 1/4 as high. Rates in both places then dropped, and through most of the summer, Sweden continued to have rates much lower than Massachusetts. In the late fall, the rates in Sweden increased (from close to zero) and for the first time caught up to the (increasing) rates in Massachusetts.
