The pooled SMD was 1.88 (95% CI: −0.41 to 4.18), indicating a favorable trend toward PRP.
This study contrasts with the above group by showing only a numerical trend rather than clear within-group efficacy [ 36 ].
PRP showed a trend toward better outcomes than AS, especially in studies using injectable PRP.
