Statistical analysis
REGRESSION
We conducted descriptive analyses of household and women's characteristics at baseline and children's age and sex among the control and intervention groups using proportions for categorical variables and means and standard deviations for continuous variables. We evaluated the effects of the FAARM intervention on poultry ownership, egg production, vaccination practices, and poultry shed use using mixed‐effects regression models, accounting for clustering at the settlement level. We then estimated the effects of the intervention on women's and children's egg consumption in the past 24 h using mixed‐effects logistic regression models with random effects to account for settlement‐level clustering and repeated woman/mother and child measures. Egg consumption models included fixed effects for intervention group, as well as for month of survey and Ramadan, with child‐level models additionally adjusted for child sex, child age in days, and the square root of child age, selected a priori as strong predictors to increase precision of the estimates. All child models used probability weighting to account for less frequent surveillance of children older than 18 months. To estimate the effects of the intervention in 6‐month periods, we included an intervention group by time period interaction term. We then used the In an additional observational analysis, we examined the association between poultry ownership, defined as ownership of ≥3 poultry, and women's and children's egg consumption. We used mixed effects logistic regression models controlling for intervention group, religion, wealth quintile, women's education, and child sex and age, and random effects to account for clustering and repeat measures. Covariates were chosen a priori as factors which could influence poultry ownership and egg consumption based on existing literature. An interaction term was used to assess the effect of owning poultry on egg consumption in the 6 months following the routine surveys on poultry ownership (e.g., the association of poultry ownership at the end of year 2 [May−August 2017] with egg consumption in the subsequent 6 months [September 2017−February 2018]).Causal mediation analysis was conducted using the ‘medflex’ package for R (Steen et al., Mediation analysis was conducted using R version 4.1.2 (R Core Team,
