3.3. Attrition
Following baseline, two (2/8) participants withdrew from the placebo group and five (5/12) from the probiotic group. Five participants withdrew during the 24–28 WG assessment period (three probiotic and two placebo) and two probiotic participants withdrew at delivery. The reasons for withdrawal differed for all seven participants and included bereavement/miscarriage, hospital change, did not wish to continue, green stool that was perceived to be linked to study supplement, unable to complete study activities; one participant was lost to follow-up and one withdrawn by the study staff for non-compliance. Baseline characteristics were largely similar between the completed and withdrawn groups, although dietary intake of iron was higher among the participants that withdrew from the study (data not shown).
