Achieving Motor Development Milestones at the Age of Three Months May Determine, but Does Not Guarantee, Proper Further Development

Table 4

Qualitative assessment scores (maximum score of 15) in infants at 3, 6, and 9 months in prone and supine position, reported according to neurological assessment. Results are given as median (quartiles 25–75%).
