↵* A low score is defined as being in the lowest 10%.
↵† Adjusted for gender, parity, birth weight, length and head circumference, mode of delivery, maternal hypertension, fever, age, education status, socioeconomic position, housing tenure and crowding index, car ownership and ethnicity.
↵‡ Not estimatable owing to no infants with a low score in the encephalopathic group.
Values are OR (95% CI).
