Notes: Data are presented as mean ± SD. The term Low n indicates inadequate sample size. For the 12-Item Short Form Survey physical component score (PCS) and mental component score (MCS), higher scores indicate better outcomes. P values reflect the statistical significance of the change from baseline.

AMUC, amniotic umbilical cord tissue; PRP, platelet-rich plasma.
