Fig 1 Schematic of the crossover study design: 2- to 4-week screening period, followed by two 4-week double-blind treatment periods separated by a washout period of 4 weeks. A final visit took place 7 to 21 days after the second treatment period. QD, Once daily.

Fig 4 Changes in urinary LTE4 values (SD) during treatment sequences AB (n = 32) and BA (n = 32). A, Roflumilast (500 μg once daily) + montelukast (10 mg once daily); B, placebo plus montelukast (10 mg once daily). Mean (SD) values were measured at baseline period 1, day 28, baseline period 2, and day 84.
