-
Two consecutive tests, one month apart, were performed in 81 of the 102 infants initially included.
-
V˙maxfrc = maximal flow at functional residual capacity ; CV = coefficient of variation ; PD15Ptco 2 = mean provocative methacholine dose for Ptco 2 (geometric mean); PD30V˙maxfrc = mean provocative methacholine dose for V˙maxfrc (geometric mean).
