Summary: | Background Departures from randomized treatments
complicate the analysis of many randomized controlled trials. Intention-to-treat
analysis estimates the effect of being allocated to treatment.
It is now possible to estimate the effect of receiving
treatment without assuming comparability of groups defined by actual treatment.
However, the methodology is largely confined to trials where the only treatment
changes were switches to other trial treatments. |
