Reliability and accuracy of the 7-item and 6-item ACQ in measuring asthma control in Greek children

Instrument	Baseline score mean (SD)	Difference in baseline scores mean (SD)	Change to follow-up mean (SD)	Difference in change mean (SD)	Baseline Cronbach alpha
7-Item ACQ	0.36 (0.36)	Ref	–0.14 (0.03)	Ref	0.67
6-Item ACQ (excluding FEV₁ level)	0.32 (0.39)	0.04 (0.03) P = 0.08^*	–0.13 (0.07)	–0.01 (0.10) P = 0.042^*	0.75

^* P-values estimated using Wilcoxon signed-rank test. Ref: reference group. P < 0.05 represents a significant difference in results
