Did lockdown rules in nursing homes save lives or cost lives?

This study looked at how strictly nursing homes in France followed COVID-19 safety rules, like visitor bans and room confinement, and whether that affected how many residents died. Researchers tracked over 12,000 residents for a year to see if strong rules lowered COVID deaths but potentially increased deaths from other causes like social isolation, especially in areas with fewer virus cases. The goal was to learn which safety approaches worked best to protect vulnerable elderly people overall.
