Composite outcome measures, such as CST and iADRS, combine the joint evolution of function and cognition over time in the population of interest when calculating the combined treatment effect.

It would be much better if the whole curve is covered by a single smooth function. Several functions of different complexity were tested. The best results were achieved with a composite function of ...
