coma prognosis is not good. see here under [Duration of coma] (https://jnnp.bmj.com/content/71/suppl_1/i20). of those who have survived a week in coma (a small minority), half are in a persistent vegetative state..

OP asked about accident-induced coma, while this study specifically excludes trauma-induced comas, concentrating on comas arising from medical conditions like diabetes, heart attack, or stroke.

I looked around a bit, and while I wasn't able to find any relevant papers quite as explicit as this is one, from what I found it doesn't look like the odds of recovery from trauma-induced comas are much better, and they may be worse.
