Favipiravir vs no treatment, supportive treatment, or other antiviral treatment

All‐cause mortality – at 28 to 30 days, or in‐hospital · people with confirmed COVID‐19

It is very uncertain whether favipiravir changes all‐cause mortality – at 28 to 30 days, or in‐hospital compared with no treatment, supportive treatment, or other antiviral treatment (very low certainty).

1 finding from 1 review

Intervention not reported

All‐cause mortality at day 28 · unvaccinated, non‐hospitalized people with mild symptomatic COVID‐19 (WHO scale 2 to 3) at high risk for progression to severe disease

The intervention may leads to lower all‐cause mortality at day 28 (low certainty).
