evidence: A small improvement in the ESAS QoL-score (i.e. decrease in ESAS-score) among the vitamin D treated patients was observed after one month, eliminating the difference between the two groups; -1.4 (95% CI -2.6-(-0.21) (Tables 2 and 3, Fig 2B). After three months no further significant changes in either group were seen.
intervention: vitamin D 4000 IE/day
