Morbidity symptoms data collection
BLIND
At each biweekly visit in Ghana (Adu‐Afarwuah et al., In Ghana, field workers unable to complete the morbidity data collection on the usual 14‐day schedule (typically because of a participant's travel) had up to 7 days to complete the visit or else consider it missed. At the first home visit 14–21 days after enrolment, field workers collected data ‘since enrolment’; in subsequent visits, data were collected ‘since last visit’ if the current visit occurred within 7–21 days after the preceding visit, or ‘during the past 2 weeks’ if the current visit occurred >21 days after the preceding visit. With this data collection scheme, it was possible to obtain self‐reports of women's morbidity over all or nearly all of the entire follow‐up period.In Malawi, the first home visit was completed within 7–13 days after enrolment, the second occurred 7 or 14 days after the first visit, and subsequent visits were completed every 14 days thereafter. At Weeks 32 and 36 of pregnancy, supplement delivery and data collection were accomplished during the women's visits to the laboratory. Although women were visited biweekly, the recall of self‐reported morbidity was conducted over the ‘past 7 days’ because of fears that recall over a longer period might be problematic due to a low average level of education.It was not possible to blind field workers or study participants to those who received the SQ‐LNSs, because the capsules (IFA and MMN) and SQ‐LNS sachets looked different. As we described previously (Adu‐Afarwuah et al.,
