Missing data for ACQ7 score in n=132. Adequate control (ACQ7≤1.5) was the reference group for the binary logistic regression analyses. ACQ7 tertiles were as follows: lowest=0–2.41; middle=2.42–3.50; highest=3.51–5.85; the lowest ACQ7 tertiles was the reference group in the multinomial regression analyses.
