The analysis of clinical trials in delirium is typically complicated by treatment dropouts and by the fact that even untreated individuals may have a good prognosis. These features of delirium trials warrant special statistical attention; implications for each stage of a trial planning process are described. ⋯ It is hoped that the methods described, and nonlinear models in particular, will play a part in convincing analyses of future delirium research.
