Oct 20, 2022 Interrupted time series should be used when longitudinal data (outcome over time - observations before and after the intervention) full population was affected at one specific point in time (or can be stacked based on intervention) In each ITS framework, there can be 4 possible scenarios of outcome after an intervention No effects Immediate effect.
