Effectiveness for sprifermin versus placebo in symptom alleviation. Forest plots of the mean difference (MD) with 95% confidence interval (CI) in WOMAC score (WOMAC total score, WOMAC pain score, WOMAC function score, WOMAC stiffness score) between patients undergoing sprifermin injection and placebo injection. (The three or four effect sizes for each trial in the figure represent the different dose of sprifermin treatment in the same trials)
