  1. aThe “change from baseline” in octogenarians was compared to patients aged <80 years using an independent samples t test and corrected for the baseline component score, where † indicates p > 0.05
  2. bAn effect size of <0.20 can be considered as clinically irrelevant, 0.20–0.49 as small, 0.50–0.79 as moderate and > 0.80 as large. PCS = physical component score, MCS = mental component score, MCID = minimal clinically important difference
