Fig. 6From: Is platelet-rich plasma an ideal biomaterial for arthroscopic rotator cuff repair? A systematic review and meta-analysis of randomized controlled trialsAmerican Shoulder and Elbow Surgeons (ASES). A fixed-effects model was used because of no heterogeneity (I2 = 26%). The dark diamond intersects the vertical line, indicating that ASES was higher after PRP application than control groups. (CI, confidence interval; df, degrees of freedom; I2, heterogeneity test; IV, inverse variance; PRP, platelet-rich plasma; SD, standard deviation; z, P value of weighted test for overall effect)Back to article page
