METHODS
Identification of studies
We sought completed randomised controlled trials
reporting outcomes on the comparative efficacy and/or
safety of different PPI drugs for GERD. We searched for
randomised trials comparing dexlansoprazole or esomeprazole
with placebo or any of the following drugs (as primary
treatment): omeprazole, pantoprazole, lansoprazole
and rabeprazole. Eligible studies must be randomised
controlled trials that have compared dexlansoprazole or
esomeprazole with a common comparator, which could
be placebo or another PPI drug. In addition, the eligible
trials should have included patients with GERD (including
EO or NERD) and reported the outcomes related to
healing data. Studies comparing treatment combinations
or only comparing different doses of a single drug were
excluded
