https://www.selleckchem.com/products/az191.html Metastatic renal cell carcinoma (mRCC) is the most common type of kidney cancers. Disease-specific survival for mRCC has been significantly improved with the introduction of new targeted agents since 2005. However, there is a lack of head-to-head clinical trials comparing the efficacy between therapies. This study compared indirectly progression-free survival (PFS) and overall survival (OS) among first-line and second-line therapies in patients with mRCC using network meta-analysis (NMA). The PubMed, MEDLINE, Cochrane Library and Web of Science were searched to identify phase II or phase III randomized controlled trials (RCTs) of targeted and biological therapies in patients with mRCC published between January 2000 and June 2020. The Bayesian fixed-effect NMA was performed to evaluate relative PFS and OS of first-line and second-line therapies of axitinib, bevacizumab, cabozantinib, everolimus, lenvatinib, nivolumab, ipilimumab, pazopanib, sorafenib, sunitinib, temsirolimus, tivozanib, avelumab and pembroine therapy in the management of mRCC. Regarding safety, avelumab + axitinib and temsirolimus were considered preferred treatment options in first-line and second-line therapies. More future research is needed to establish subgroup analyses, allowing evaluation of the impact of some of the differences in patient characteristics, including treatment effect modifiers.Functional analyses are intended to identify the reinforcers maintaining problem behavior in order to inform clinicians' selection of interventions. Traditionally, these analyses have exposed problem behavior to multiple, isolated reinforcement contingencies and in doing so, have ruled in and ruled out potential sources of reinforcement. Recently, some functional analysis models have forgone testing individual reinforcement contingencies and instead exposed problem behavior to 2 or more reinforcers simultaneously in a single, synthesized reinforcement contin
