*P<0.05, chi-square test from binomial regression with identity link.
**P<0.0001, chi-square test from binomial regression with identity link.
Series completion was calculated for only those children with dose 1; variable constructed from manufacturers' recommendations.
Timeliness was constructed from manufacturers' recommendations.
The likelihood ratio test comparing adjusted models 1 and 2 was not significant for the outcome “PCV series completion,” indicating that the fit did not improve with the addition of the interaction term.
