Hold up. Who the heck thought it was a good idea to put masking policy on the Y axis and deaths on the X axis. Also what the heck does Y% mask compliance mean?

Hold up. Who the heck thought it was a good idea to put masking policy on the Y axis and deaths on the X axis. Also what the heck does Y% mask compliance mean? Does that mean Y% of people wore it 100% of the time and (1-Y%) wore it never? Or does it mean if you picked a random person at a random time, there was a Y% chance they were wearing a mask? There's a distinct lack of clarity in what exactly is being tested here. I agree with the ranking the paper has gotten so far in the side bar. Its weak point is its study design and methods. Frankly, that part reads like someone who furiously googled some data to win an online argument, not like a scientific paper.
