    I think just a sample size negates “weaker immune system vs stronger immune system/ less preconditions vs more preconditions”.

    We built a cohort of 138,818 individuals with SARS-CoV-2 infection and 5,985,227 noninfected control group from the US Department of Veterans Affairs and followed them for 2 years to estimate the risks of death and 80 prespecified postacute sequelae of COVID-19 (PASC) according to care setting during the acute phase of infection.

      Why would the sample size negate it?

      If you assume that people with stronger immune system and less preconditions are less likely to catch COVID, or notice having caught it, surely the sample size does nothing to prevent this bias?

        That is outside of the paper scope. They researched people that did tested positive and compared long term effects between mild cases, those with hospitalizations and those that weren’t infected.
