Clinical Implications of Oscillatory Lung Function during Methacholine Bronchoprovocation Testing of Preschool Children

Table 2

Baseline measurements of lung function at challenge test 1 and challenge test 2.

	1st set	1st set CV	2nd set	2st set CV	SDw	CV (%)	ICC
Rrs5 (kPa/L/sec)					0.37	4.64	0.88 (0.76–0.94)
Rrs10 (kPa/L/sec)					0.31	4.29	0.87 (0.74–0.94)
Xrs5 (kPa/L/sec)					0.29	5.78	0.81 (0.61–0.91)
Xrs10 (kPa/L/sec)					0.31	10.35	0.73 (0.46–0.87)
AX (kPa/L)					0.98	11.21	0.85 (0.71–0.93)
Rf (Hz)					1.37	3.36	0.76 (0.52–0.88)

CV, coefficient of variation; SDw, within-subject SD (SD of the mean difference between the 1st and 2nd sets divided by √2); CV (%), CV between the first and second sets; ICC, intraclass correlation coefficient (between-subject variance divided by the total variance).
