Systematic review and meta-analysis: Proton pump inhibitors slightly decrease the severity of chronic cough

This systematic review and meta‑analysis examined the effects of acid-suppressive medications in adults with non-specific chronic cough, based on data derived from 11 double-blind, placebo-controlled, randomized trials. The authors noted that, from a research standpoint, additional high-quality trials that "employ validated objective cough monitoring tools, such as the Leicester Cough Monitor and VitaloJAK should be conducted".
