Dataset from Effect of Positive Airway Pressure on Reducing Airway Reactivity in Patients With Asthma

The CPAP trial is a 3-arm parallel design randomized sham-controlled trial. Participants are randomly assigned in equal allocation to one of three treatments: CPAP 10 cm water (H₂O) (high) vs. CPAP 5 cm H₂O (medium) vs. CPAP Sham (less than 1 cm H₂O, Low). The treatment period is 12 weeks with airways reactivity assessed at baseline, 6 and 12 weeks of treatment and after a 2 week washout.
