Are Asthmatics Enrolled in Randomized Trials Representative of Real-Life Outpatients?

Abstract

In a real-life setting, >40% of subjects with mild/moderate asthma are currently treated by protocols based on the results of RCTs for which they would not have been eligible. This proportion increases in elderly patients with comorbidities. These findings limit the generalizability of RCTs and advocate that complementary pragmatic studies be conducted. © 2015 S.
