Study design details

Main study objective

To study the association between oral bisphosphonate use and 1.fracture risk (ie benefits) and 2.known adverse events amongst patients with CKD.

Outcomes

1. CKD progression, 2 osteoporotic (all but face/skull/fingers/toes) fracture/s. 3.acute kidney injury, hospitalization for hypocalcemia/hypophosphataemia, or upper gastro-intestinal events, and 4: annualized hip BMD % change. CKD progression as based on eGFR changes over time.

Data analysis plan

BP use will be introduced as a time-varying exposure. Cox regressionstratified by propensity matched sets will be used to estimate the association between BP use and the study outcomes(WP1/2/3). Linear regression models will be fitted to study the association between BP use and hip BMD in CKD patients(WP4).A more detailed analysis plan is available in the enclosed study protocol.
