“…Systematic review and network meta-analysis (NMA) studies have investigated the relative efficacy of the following IAI agents, analyzed in pairs: CSs [ 11 , 12 , 13 , 14 , 15 , 16 ], HA [ 12 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ], PRP [ 11 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 23 , 24 , 25 ], plasma rich in growth factor (PRGF) [ 12 , 13 ], botulinum neurotoxin type A (BoNTA) [ 12 , 18 , 23 ], ozone (OZ) [ 12 , 16 , 20 , 21 ], dextrose prolotherapy (DxTP) [ 18 , 23 ], MSCs [ 12 , 14 , 24 , 25 , 26 ], stromal vascular fraction of adipose tissue (SVF) [ 12 , 25 , 26 ], and autologous conditioned serum (ACS) [ 12 , 23 , 25 ]. However, none of these IAI agents have been comprehensively compared with others in a single NMA study, and thus, the overall relative efficacy of each remains unclear [ …”
