Table 2 Quality assessment and summary the findings for the primary outcomes in developing countries

Outcomes	№ of participants (studies)	Quality of the evidence (GRADE)	Anticipated absolute effects
Outcomes	№ of participants (studies)	Quality of the evidence (GRADE)	Risk with MWH	Risk with Non MWH	Risk difference with MWH
Maternal death	32,592 (7 observational studies)	⨁⨁⨁◯ MODERATE	1 per 1000 (11/10,129)	10 per 1000 (223/22,463)	9 fewer per 1000 (10 fewer to 8 fewer)
Stillbirth	27,342 (5 observational studies)	⨁⨁⨁◯ MODERATE	17 per 1000 (139/7968)	181 per 1000 (3508/19374)	164 fewer per 1000 (166 fewer to 159 fewer)

GRADE Working Group grades of evidence
High quality: We are very confident that the true effect lies close to that of the estimate of the effect
Moderate quality: 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 quality: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect
Very low quality: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect
