Patients 50\u2009years and older with a diagnosis of \u201cmenopause\u201d and \u201costeoporosis\u201d were included in this study. Odds ratios (OR) and 95% confidence intervals (CI) were calculated for new GERD, esophageal stricture and Barrett's esophagus after raloxifene exposure. The control cohort consisted of patients who did not start any hormonal replacement therapy. We conducted a multivariable logistic regression analysis to evaluate the effect of confounding variables and also addressed common confounding medications with 1:1 propensity score\u2010matching. Internal validity was confirmed by comparing to negative controls (lisinopril, atorvastatin) and positive controls (metformin, ibuprofen, aspirin).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Five thousand four hundred and seventy two postmenopausal women with osteoporosis were on raloxifene of which 1908 (34.86%) developed GERD, compared to 296,067 postmenopausal who were not on raloxifene of which 90,643 (30.62%) developed GERD (OR 1.2; 95% CI 1.10\u20131.31, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001). This persisted after adjusting for common medications known to affect GERD. Raloxifene was identified as a risk factor for GERD in a multivariate analysis, controlling for factors including age, obesity, smoking, and alcohol use (OR 1.51, 95% Wald CI 1.47\u20131.53). Raloxifene was associated with esophageal stricture (OR 1.60; 95% Wald CI 1.51\u20131.69) and Barrett's esophagus (OR 1.50; 95% Wald CI 1.37\u20131.63) in multivariate analysis.
