Table II.

Mean±SD height, weight and BMI Z-scores and FEV₁ percent predicted at the 6-month and 1-year follow ups for the cases and controls.

	6 months			1 year
	Cases	Controls	p-value^a	Cases	Controls	p-value^a
Height Z-score	−0.89±0.56	−0.48±1.00	0.77	−0.84±0.53	−0.51±1.00	0.29
Weight Z-score	−0.73±0.79	−1.01±0.76	<0.001	−0.76±0.73	−0.86±0.70	0.01
BMI Z-score	−0.29±0.84	−1.02±0.67	<0.001	−0.41±0.76	−0.71±0.51	0.07
FEV₁	74.7±22.0%	78.9±24.0%	0.46	74.4±21.4%	82.3±22.9%	0.17

The p-value is from a paired t-test comparing the difference between the cases and controls in the change in the parameter from the time of the index visit to the specified follow-up visit.
