  1. Note: This remodified version of RTS was raised according to results in the meta-analyses and remodifications on the cut-off of KPS (a) and number of involved vertebrae (b) were conducted for the scoring system. The patients with KPS 10–40/ 50–70 and patients with single/double involved vertebrae were merged together
