Power and sample size calculations for longitudinal studies comparing rates of change with a time-varying exposure
Existing study design formulas for longitudinal studies have assumed that the exposure is time-invariant. We derived sample size formulas for studies comparing rates of change by exposure when the exposure varies with time within a subject, focusing on observational studies where this variation is n...
