Power and sample-size calculations for trials that compare slopes over time: Introducing the slopepower command
Trials of interventions that aim to slow disease progression may analyze a continuous outcome by comparing its change over time—its slope—between the treated and the untreated group using a linear mixed model. To perform a sample-size calculation for such a trial, one must have estimates of the para...
