For people who are curious about this and want to read further than the original Ioannidis and the Meyerowitz-Katz papers, here are two citations I found enlightening. The first is a frequentist analysis that is age-stratified, so is likely to control for the rather different age structures in different countries[1]. The second is a Bayesian approach[2]. Both seem pretty reasonable to me, and don't display obvious axes to grind.
