Fig. 2

Average a physical function (HAQ score) and b HRQoL (EQ-5D score) of HKOA participants at baseline and in each follow-up wave (EpiDoC 2, 3, and 4). Data labels are mean (standard deviation). PA, physical activity. Sample size not consistent due to missing values: physical function EpiDoC2—all (n = 953), no (n = 751), frequent (n = 62), very frequent (n = 140); physical function EpiDoC3—all (n = 728), no (n = 567), frequent (n = 50), very frequent (n = 111); physical function EpiDoC4—all (n = 408), no (n = 297), frequent (n = 36), very frequent (n = 75); HRQoL EpiDoC1—all (n = 1073), no (n = 845), frequent (n = 67), very frequent (n = 161); HRQoL EpiDoC2—all (n = 959), no (n = 748), frequent (n = 61), very frequent (n = 141); HRQoL EpiDoC3—all (n = 719), no (n = 559), frequent (n = 50), very frequent (n = 110); HRQoL EpiDoC4—all (n = 405), no (n = 293), frequent (n = 37), very frequent (n = 75). Kruskal–Wallis test for the difference between physical activity categories: HAQ—EpiDoC 1 (p < 0.001), EpiDoC 2 (p < 0.001), EpiDoC 3 (p < 0.001), EpiDoC 4 (p = 0.005); EQ-5D—EpiDoC 1 (p < 0.001), EpiDoC 2 (p < 0.001), EpiDoC 3 (p < 0.001), EpiDoC 4 (p = 0.134)
