At risk of deficit	65	34	14,2	31	12.9
Normal	248	120	50.0	128	53.3

*The data was grouped according to presumptive diagnosis as deficit (lower than percentile 3), at risk of deficit (≥ percentile 3 and < percentile 10), normal (≥ percentile 10 and ≤ percentile 90), at risk of excess (> percentile 90 and ≤ percentile 97), and excess (> percentile 97).
