The objective of this network meta-analysis (NMA) was to assess the pain relief performance of eight different plantar fasciitis therapies, including nonsteroidal anti-inflammatory medications, corticosteroid injections (CSs), autologous whole blood, platelet-rich plasma (PRP), extracorporeal shockwave therapy (ESWT), ultrasound therapy (US), botulinum toxin A (BTX-A), and dry needling (DN). Published prospective or randomized controlled trials (RCTs) as for the above eight therapies were identified by searching CNKI, PubMed, and Embase. Mean difference (MD) and 95% credible intervals (CrIs) of visual analogue scale (VAS) were used to evaluate multiaspect comparisons. The ranking result was obtained by utilizing surface under cumulative ranking curve (SUCRA). Node-splitting plots were conducted to assess the consistency between direct and indirect evidence. Egger's test and funnel plots were performed to examine publication bias. Forty-one trials with a total of 2,889 cases were involved in this NMA. In terms of 1-month VAS, only ESWT turned out to be of better efficacy than placebo (MD = -3.3; CrI: [-5.3, -1.1]). No statistically significant difference was found between pair-wise comparisons concerning 2-month VAS. ESWT also demonstrated better efficacy as for 3-month results (MD = -2.7; CrI: [-4.2, -1.3]). Besides, CSs was significantly better than placebo as well in 3-month results (MD = -2.1; CrI: [-4.1, -0.19]). With regard to 6-month VAS results, ESWT performed better than placebo (MD = -3.0; CrI: [-5.0, -0.51]). According to the SUCRA, ESWT ranked the first as for all seven outcomes. ESWT might be the optimal treatment. In addition, BTX-A and PRP were considered as suboptimal.
