Studies were included if they compared PRP to another injectable and were excluded if they did not report complications. Summary statistics and number needed to harm were calculated. Meta\u2010analyses were conducted using DerSimonian\u2010Laird random\u2010effects models, reported in odds ratios (OR).

There was a total of 615 patients, 298 of whom underwent PRP injections. Four studies reported zero complications. No severe complications were reported.
