Are psychiatric disorders risk factors for COVID-19 susceptibility and severity? a two-sample, bidirectional, univariable, and multivariable Mendelian Randomization study https://www.nature.com/articles/s41398-021-01325-7 https://www.nature.com/articles/s41398-021-01325-7 Some studies found links, some didnt, all depends on how you slice the data. I would imagine quite difficult to get a sense when the major risk factors (age and weight) are so dominant.
