Knowledge and practice scores of mothers in nutrition education group and no nutrition education group at pre- and post-intervention. Table S6. LMMs and GLMMs for the change of K- and P-Scores, DDS, and Hb of mothers from pre- to post-intervention, and MDD-W and dietary modifications at post-intervention. Table S7.
