Clinical outcome measures	RPG	CG	p value
Clinical outcome measures	Mean difference (95% CI)	Mean difference (95% CI)	p value
BMI, kg/m²	−1.10 (−3.58 to 1.37)	0.08 (−0.03 to 0.20)	0.868
WOMAC pain (0–20)	0.85 (0.44 to 1.27)	0.23 (−0.01 to 0.49)	0.016
WOMAC stiffness (0–8)	0.71 (0.50 to 0.92)	0.21 (−0.03 to 0.45)	0.002
WOMAC physical function (0–68)	0.11 (−0.05 to 0.29)	0.11 (−0.05 to 0.29)	0.576

RPG, rehabilitation protocol group; CG, control group; BMI, body mass index; WOMAC, Western Ontario and McMaster Universities Osteoarthritis Index; CI, confidence interval.
