Ages corrected for the preterm born infants. Numbers in brackets = range of SATCo scores
^aThe numbers represent medians of the SATCo trunk segmental level at which control was being learnt: 1 = head control, 2 = upper thoracic level, 3 = mid-thoracic, 4 = lower thoracic, 5 = upper lumbar, 6 = lower lumber, 7 = full trunk control, and 8 = full trunk control achieved. Please note that the SATCo is an ordinal scale and the learning levels shown in this table were the medians of each group of infants at each month. The non-integral numbers reported in the table were purely for statistical purposes. In real life situations, no half-level would be credited to the infants
