Power calculator for instrumental variable analysis in pharmacoepidemiology

BACKGROUND: Instrumental variable analysis, for example with physicians’ prescribing preferences as an instrument for medications issued in primary care, is an increasingly popular method in the field of pharmacoepidemiology. Existing power calculators for studies using instrumental variable analysi...
