^ep-values for between-group differences in associations of physical and mental component summaries with motor skills

HRQoL = health-related quality of life, VLBW = very low birth weight, CI = confidence interval

MABC-2 = Movement Assessment Battery for Children-2, HiMAT = High-level Mobility Assessment Tool

Higher scores on the Grooved Pegboard and Trail Making Test-5 indicate poorer function and higher scores on the MABC-2 and HiMAT indicate better function
