Columns, from left to right, are: subject id; number of the measurement; age (in months at measurement); estimate of EEG abnormality (0 = normal, 1 = mild, 2 = abnormal); EEG findings; AP, attention problems (0 = not observed, 1 = present); MP, motor problems (0 = not observed, 1 = present); Epi., epilepsy symptoms (0 = no, 1 = yes); drug treatment (no long-term treatment = N, valproate = V, carbamazepine = C, antibiotics = A).
