 Crude and adjusted odds ratio (OR) with 95% confidence intervals (CI) as an estimate of the relative risk of motor problems, defined by a score below the 5th centile on the Movement assessment battery for children (Movement ABC) in two groups of low birthweight children compared with a control group

*OR cannot be computed because of the value 0 in one cell.
VLBW, Very low birth weight; SGA, small for gestational age; CP, cerebral palsy.
