^¤Adjusted for clustering to account for the PROMISE-EBF study design.

^§Adjusted for clustering and for all variables in the table
^‡Includes only multiparous mothers
Overall, pauciparae women (nulliparous and primiparae), twins and a birth during the dry season were the factors significantly associated with the risk of perinatal death in this cohort.
