It's notable as well when evaluating Sweden's number is that they are far more trustworthy than most countries. One interesting metric is excess mortality. Some places have wild unexplained excess mortality from the statistical expectation, that isn't fully explained by reported Covid-19 deaths. This suggests that Sweden is reporting deaths far more accurately than other countries, so when we evaluate the relative success of their strategy, we should keep that in mind.
