Notes: Data are presented as mean ± SD. The term Low n indicates inadequate sample size. The visual analog scale is scored from 0 to 10, with 0 indicative of no pain and 10 indicative of the most severe pain. P values reflect the statistical significance of the change from baseline.
AMUC, amniotic umbilical cord tissue; PRP, platelet-rich plasma.
