Summary of findings
(last update: 2022-11-22)

Patient or population: COVID-19 patients
Setting: Worldwide
Intervention: Molnupiravir
Comparison: Standard care/Placebo

Outcome	Relative effect (95% CI)	Absolute effect (95% CI)¹		Certainty of the Evidence (GRADE)
Clinical improvement D28	RR: 1.12 (1.07 - 1.18)	95 more per 1000 (from 56 more to 143 more)		Low certainty Reasons to downgrade Risk of bias: Not serious Inconsistency: Not serious Indirectness: Serious despite a multicentre design this is a single study from a single country, therefore results in this population might not be generalizable to other settings. Imprecision: Serious due to low number of participants/events
1 trials Koudinya Tippabhotla S, 2022 1220 participants		Molnupiravir 890 per 1,000 (851 - 938)	Standard care/Placebo 795 per 1,000	1 additional study was identified that assessed this outcome, but no results were reported.
Clinical improvement D60	Outcome not yet measured or reported
Hospitalisation or death	RR: 0.80 (0.56 - 1.15)	3 fewer per 1000 (from 6 fewer to 2 more)		High certainty Reasons to downgrade Risk of bias: Not serious Inconsistency: Not serious Indirectness: Not serious Imprecision: Not serious
5 trials Caraco Y, 2021; Jayk Bernal A, 2021; Koudinya Tippabhotla S, 2022; Khoo SH, 2022; Butler C, 2022 28766 participants		Molnupiravir 10 per 1,000 (7 - 15)	Standard care/Placebo 13 per 1,000
WHO progression score (level 7 or above) D28	RR: ( - )	Zero events in both groups		Low certainty Reasons to downgrade Risk of bias: Not serious Inconsistency: Not serious Indirectness: Not serious Imprecision: Very serious no events in both groups
2 trials Koudinya Tippabhotla S, 2022; Khoo SH, 2022 1400 participants		Molnupiravir 0 per 1,000 ( - )	Standard care/Placebo 0 per 1,000
WHO progression score (level 7 or above) D60	Outcome not yet measured or reported
All-cause mortality D28	RR: 0.27 (0.09 - 0.82)	1 fewer per 1000 (from 1 fewer to 0 fewer)		High certainty Reasons to downgrade Risk of bias: Not serious Inconsistency: Not serious Indirectness: Not serious Imprecision: Not serious
7 trials Koudinya Tippabhotla S, 2022; Caraco Y, 2021; Jayk Bernal A, 2021; Fischer W, 2021; Khoo SH, 2022; Butler C, 2022; Zou R, 2022 28999 participants		Molnupiravir 0 per 1,000 (0 - 1)	Standard care/Placebo 1 per 1,000	1 additional study was identified that assessed this outcome, but no results were reported.
All-cause mortality D60	Outcome not yet measured or reported
Viral negative conversion D7	RR: 2.26 (0.86 - 5.97)	141 more per 1000 (from 16 fewer to 555 more)		Very low certainty Reasons to downgrade Risk of bias: Serious Risk of bias downgraded by 1 level: some concerns or high risk regarding adequate randomisation, deviation from intenden intervention, missing data and selection of the reported results Inconsistency: Very serious Inconsistency downgraded by 2 levels: I²=:97.4% Indirectness: Not serious Imprecision: Serious due to wide confidence interval consistent with the possibility for benefit and the possibility for no effect/trivial effect
6 trials Koudinya Tippabhotla S, 2022; Jayk Bernal A, 2021; Fischer W, 2021; Khoo SH, 2022; Butler C, 2022; Zou R, 2022 3006 participants		Molnupiravir 252 per 1,000 (96 - 666)	Standard care/Placebo 112 per 1,000
Adverse events	RR: 0.99 (0.90 - 1.09)	3 fewer per 1000 (from 27 fewer to 24 more)		Moderate certainty Reasons to downgrade Risk of bias: Not serious Inconsistency: Not serious Indirectness: Not serious Imprecision: Serious due to low number of participants/events
6 trials Koudinya Tippabhotla S, 2022; Caraco Y, 2021; Jayk Bernal A, 2021; Fischer W, 2021; Khoo SH, 2022; Zou R, 2022 3216 participants		Molnupiravir 265 per 1,000 (241 - 292)	Standard care/Placebo 268 per 1,000	1 additional study was identified that assessed this outcome, but no results were reported.

¹The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI)

CI: Confidence interval; RR: Risk ratio

GRADE Working Group grades of evidence
High certainty: We are very confident that the true effect lies close to that of the estimate of the effect
Moderate certainty: We are moderately confident in the effect estimate: The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different
Low certainty: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect
Very low certainty: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect
