Core Tip

Core tip: As a kind of powerful and effective acid-suppressive drugs, proton pump inhibitor (PPI) has been used for patients with non-erosive reflux disease (NERD), but its efficacy, safety and their influential factors are inconclusive. We performed this systematic review and meta-analysis of randomized controlled trials to assess its efficacy, safety and influential factors. Based on the results of the meta-analysis, we conclude that PPI has a higher symptomatic relief rate and roughly the same adverse rate for NERD. Hiatal hernia and drinking could influence symptomatic relief rate and adverse rate of PPI on NERD.
