Association of COVID-19 with diabetes: a systematic review and meta-analysis

Well, I have read that Covid-19 is about eight times more deadly for diabetics than for other people.
So, it makes sense that a diabetes drug would help diabetics to survive Covid. Metformin doesn’t actually have antiviral effects. But by controlling the diabetes that predisposes people to die, it helps indirectly.
Thanks.
