n, number of observations (measures) from visit1 to visit5.
Multi‐level mixed‐effects model estimated the monthly change in growth outcomes (SE), adjusting for child age and sex, district location, and data collector who surveyed the household, father's education, household wealth status, household food security, type of nearest health facilities and mobile phone availability.
Differences (95% CI) in monthly change of growth outcomes between control and intervention areas were derived using contrasts of average marginal effects.
