2Does the study focus on the food voucher (cash value voucher or food package for WIC) component of the programme?
3Does the study focus on beneficiaries (women who were receiving the vouchers) rather than eligibility status (women who were eligible to receive the vouchers)?
4Does the sample include pregnant women?
5If the sample does not include pregnant women, could some of the findings be generalisable to pregnant women?
6Does the study report women's food or nutrient intakes (measured or perceived)?
7Does the study provide any insights about how food vouchers are used?
8Does the study provide any insights about which women may benefit most/least and why?
