Notes: *Minimum wage (MW) BRL 1,212.00. ** Referral to high-risk prenatal care (HRPN). Each relation between the outcome and the predictor was
adjusted for age, education, and referral to HRPN (or two of them, when one of the adjustment variables was used) by the Poisson regression model
with robust variance.
Abbreviations: CI: Confidence interval; PR: Prevalence ratio; APNCU: Adequacy of prenatal care utilization.
