When a GerdQ cutoff score was set at 8, GerdQ significantly predicted the presence of reflux oesophagitis. Although the GerdQ scores were correlated with the CDQ scores, the concordance rates were poor. Multivariate analysis results indicated that, the additional use of over\u2010the\u2010counter medications was associated with GerdQ score\u2009\u2265\u20098, but not with CDQ score\u2009\u2265\u20096.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The GerdQ cutoff score of 8 was appropriate for the Japanese population.
