Fig. 2.

A plot of the spline function trajectory of estimated score values reported for deceased patients, for each PROMIS domain. All mean score values are plotted, with dates of assessment indexed by months prior to death along the horizontal access, and mean domain score values represented on the vertical axis, for each PROMIS domain. The spline function trajectory of estimated score values is depicted by bars plotted for each assessment date, superimposed on the scatterplot of all score values
