All correlations were statistically significant ( p< 0.001). Supplementary Table S2 : Influence of baseline characteristics on 2-year osteophyte change after knee joint distraction treatment Unstandardized coefficient ( B ) Standardized coefficient ( β ) P- value Age 0.166 0.092 0.495 Sex -2.158 -0.075 0.570 BMI -0.071 -0.018 0.890 Kellgren-Lawrence grade 2.423 0.160 0.330 Analyses performed using linear regression; the influence of baseline characteristics (age, sex, BMI, Kellgren- Lawrence grade) was corrected for baseline osteophyte size. Not correcting for baseline values did not change significance. BMI: body mass index.
