The Australian-led review of 32 studies with more than 2300 participants has found the treatments are associated with only a 1.6% improvement in pain.

Pooled data from eight trials showed that, three months after intervention, mean pain scores on a 10-point scale (where zero was best) was 3.7 points with placebo and 0.16 points better with autologous blood or platelet‐rich plasma (PRP) injection, a non-significant improvement.
