Rate Ratios (RR) calculated by negative binomial regression models and adjusted for sex, maternal educational level, monthly income, household electric appliances, water source, bathroom facility, crowding, and number of follow-up evaluations.
Abbreviations: CI = Confidence Interval.
Parameters were estimated and statistical comparisons were performed using negative binomial distributions.
