Comparative efficacy and safety of traditional Chinese medicine for lipodermatosclerosis A protocol for systematic review and network meta-analysis

Background: Lipodermatosclerosis (LDS) is a severe skin change accompanied by the development of chronic venous disease of the lower extremities. Its main clinical manifestations are erythema, induration, hyperpigmentation, and rough and thickened skin. It may also eventually lead to refractory ulcers, skin necrosis and even cancer. Conventional treatment methods mainly include the intake of oral anabolic hormones or androgen and pressure therapy. However, patients often refuse due to their drug resistance and intolerance. As a clinical irreplaceable treatment method for LDS, traditional Chinese medicine (TCM) has not been compared of the safety and effectiveness so far. Therefore, we cannot wait to use a method to compare the efficacy of TCM for LDS systematically, such as network meta-analysis (NMA). Methods: We will retrieve the relevant Chinese and English databases comprehensively. All the randomized controlled trials of TCM for LDS from January 2015 to September 2020 will be included. Under the guidance of inclusion criteria, 2 researchers will screen the literature, then assess the risk of bias and extract data. We will use Bayesian NMA to evaluate all available evidence in STATA 14.0 and WinBUGS software. Results: This study will use Bayesian NMA to evaluate the efficacy and safety of TCM for LDS. Conclusion: This study provide a reliable theoretical basis for the clinical application of TCM in the treatment of LDS, and contribute to the formulation of treatment guidelines for LDS.
