  • Children were stratified according to clinic and age group (<15 or ≥15 months) and randomized in blocks of 10 to 1 of 3 arms: (1) OS arm; (2) NS arm; (3) DS arm using age-appropriate milestones at all well-child visits. Pairwise comparisons between screening with office support and screening without office support were not statistically significant, P > .05. Data are presented n (%).
