Changes in subchondral cysts WORMS sum scores and effusion WORMS scores during the 96-month follow-up. a Changes in subchondral cysts WORMS sum scores over 96 months. b Changes in effusion WORMS scores over 96 months. Data were given as adjusted means (scores), corrected adjusted for age, sex, race and baseline BMI and K&L grades. Error bars represented standard errors. P-values in bold refer to significant differences between groups on average over 8 years, respectively: subchondral cysts sum scores (P = 0.002) and effusion scores (P = 0.001)
