Tables were based on retrospective data. There are different denominators according to data available during follow-up. Sometimes patients didn’t attend follow up.
SD, Standard Deviation. Wasi, Wechsler Abbreviated Scale of Intelligence. VMI, test of Visual Motor Integration. P50, percentile 50 (median). ICFES test, Instituto Colombiano de Fomento para la Educación Superior (state exams for university entrance in Colombia).
Chi2 or Fisher’s exact test was used for qualitative variables and Mann Whitney or Student’s t-test for quantitative variables, according to the distribution of each variable in the comparison groups.
