Improvement in functional parameters by 3 months in relation to changing preferences

Functional parameter of improvement, indicated by + for all measurements except MLHF, in which lower scores reflect less limitation	Increased survival preference at 3 months (N=86)	Decreased survival preference at 3 months (N=50)	Total number with changing preferences and repeated parameter measurement 86 + 50 = 136	P value

Table entries are mean (standard deviation) except last row. P-values from Wilcoxon rank sum tests except last, from likelihood ratio chi square.

^*Defined as increase at least 10 for visual analog scores, decrease at least 5 for MLHF, increase at least 50 feet for walk.
