On further sensitivity analyses, we observed a dose-dependent effect for all PPIs with the strongest effect in cirrhotic patients receiving a dose of >50000mg during the 5years prior to index date (OR 1.63, 95% CI 1.32-2.03). PPI use was associated with bone fractures in a dose-dependent fashion in patients with cirrhosis. PPI use in these patients should be based on a careful risk-benefit assessment.

After a simple protein precipitation with acetonitrile for sample preparation, the separation of the analytes were performed on an Acquity UPLC BEH C18 (2.1 × 50 mm, 1.7 μm) column, with acetonitrile and 0.1% formic acid in water as mobile phase by gradient elution. The detection was achieved on a triple quadrupole tandem mass spectrometer by multiple reaction monitoring mode via an electrospray ionization source. Good linearity was observed in the calibration curve for each analyte. The data of precision, accuracy, matrix effect, recovery and stability all conformed to the bioanalytical method validation of acceptance criteria of US Food and Drug Administration recommendations. The newly developed UPLC-MS/MS method allowed simultaneous quantification of VOR, fluoxetine and their metabolites for the first time and was successfully applied to a pharmacokinetic
