In all analyses, except caregiver knowledge and vaccination preference, results are adjusted for child age and sex, and the baseline
value of the outcome variable. For caregiver knowledge and vaccination preference results were adjusted for age, educational status, previous vaccination of the caregiver, and baseline responses
¹ We assessed impact in mothers/caregivers using linear regression and we report the adjusted regression coefficient. Possible scores ranged from 0鈥�21
² We assessed impact in children aged 9鈥�59 months using logistic regression and we report the adjusted odds ratio
³ Impact was assessed in children aged 12鈥�27 months using logistic regression and we report the adjusted odds ratio
⁴ We assessed impact in children aged 0鈥�59 months using logistic regression and we report the adjusted odds ratio
⁵ We assessed impact in mothers/caregivers using logistic regression and we report the adjusted odds ratio
