Application of network meta-analysis in the field of physical activity and health promotion

Continued advancement in the field of physical activity and health promotion relies heavily on the synthesis of rigorous scientific evidence. As such, systematic reviews and meta-analyses of randomized controlled trials have led to a better understanding of which intervention strategies are superior (i.e., produce the greatest effects) in physical activity-based health behavior change interventions. Indeed, standard meta-analytic approaches have allowed researchers in the field to synthesize relevant experimental evidence using pairwise procedures that produce reliable estimates of the homogeneity, magnitude, and potential biases in the observed effects. However, pairwise meta-analytic procedures are only capable to discerning differences in effects between a select intervention strategy and a select comparison or control condition. In order to maximize the impact of physical activity interventions on health-related outcomes, it is necessary to establish evidence concerning the comparative efficacy of all relevant physical activity intervention strategies. The development of network meta-analysis (NMA)—most commonly used in medical-based clinical trials—has allowed for the quantification of indirect comparisons, even in the absence of direct, head-to-head trials. Thus, it stands to reason that NMA can be applied in physical activity and health promotion research to identify the best intervention strategies. Given that this analysis technique is novel and largely unexplored in the field of physical activity and health promotion, care must be taken in its application to ensure reliable estimates and discernment of the effect sizes among interventions. Therefore, the purpose of this review is to comment on the potential application and importance of NMA in the field of physical activity and health promotion, describe how to properly and effectively apply this technique, and suggest important considerations for its appropriate application in this field. In this paper, overviews of the foundations of NMA and commonly used approaches for conducting NMA are provided, followed by assumptions related to NMA, opportunities and challenges in NMA, and a step-by-step example of developing and conducting an NMA.  相似文献   

在线医疗社区患者择医行为影响因素研究   总被引：5，自引：1，他引：4  

陆泉  李易时  陈静  李保萍 《图书情报工作》2019,63(8):87-95

[目的/意义]在线医疗社区作为新型医患互动的医疗服务平台，其中的咨询服务是社区吸引用户的重要功能，而付费咨询也是社区赢利的关键模块。了解付费咨询时患者择医行为的信息需求与影响因素，能够更好地改善医生的服务、提升社区活力。[方法/过程]基于消费者信任理论和消费者感知理论，同时考虑在线社区的研究背景，创新地加入价格和从众心理的作用，建立在线医疗社区患者择医行为的影响模型，并以好大夫在线为例，爬取网站数据进行回归分析，以验证变量之间的因果关联。[结果/结论]实证分析证实医生的线下声誉、线上口碑、服务质量、贡献价值、热度以及价格等因素对患者择医行为的影响，且患者线上择医行为也表现出与传统线下择医的差异。研究结果可为医生改进服务和平台社区促活增收提供参考建议。  相似文献   

基于社会资本理论的社交问答用户健康信息行为研究     

陆泉  刘婷  邓胜利 《图书情报工作》2019,63(17):118-127

[目的/意义]社交问答用户的社会资本受多种因素影响，本文旨在探究社交问答用户不同的健康信息行为对其社会资本积累的影响。[方法/过程]以知乎网上糖尿病话题下2 537个问题帖子，3 567个回答的1 650名用户为研究对象，依据L.Nan的社会资本理论和N.Uphoff对社会资本的分类，将社交问答用户的社会资本分为认知性和结构性两类，用多元线性回归的方法分析社会问答用户的健康信息行为与社会资本之间的关系。[结果/结论]用户的健康知识贡献行为和自我信息披露行为在不同程度上正向促进社会资本的累积，而不同的健康知识获取行为对认知性社会资本和结构性社会资本的影响有差异。这些结果有助于社交问答用户提高社会资本，平台完善用户服务和激励机制。  相似文献   

从组织学习的角度看集群     

孙庆波  全笑蕾  王亚斌 《科技创业月刊》2007,20(2):141-142

通过将资源基础观中的资源属性引入到知识的分类中去,创新性地把知识分为维持型知识、机密型知识、核心能力型知识和竞争优势型知识四类。在此基础上,构建知识转换模型,并最终形成集群学习模型,分析指出集群有利于组织从集群中获取知识,而组织学习(包括向集群内组织与集群外组织的学习)通过知识转换又会增加集群的知识存量,提升集群竞争优势。  相似文献   

A citation-based document retrieval system for finding research expertise     

Quan Thanh Tho  S.C. Hui  A.C.M. Fong 《Information processing & management》2007

Current citation-based document retrieval systems generally offer only limited search facilities, such as author search. In order to facilitate more advanced search functions, we have developed a significantly improved system that employs two novel techniques: Context-based Cluster Analysis (CCA) and Context-based Ontology Generation frAmework (COGA). CCA aims to extract relevant information from clusters originally obtained from disparate clustering methods by building relationships between them. The built relationships are then represented as formal context using the Formal Concept Analysis (FCA) technique. COGA aims to generate ontology from clusters relationship built by CCA. By combining these two techniques, we are able to perform ontology learning from a citation database using clustering results. We have implemented the improved system and have demonstrated its use for finding research domain expertise. We have also conducted performance evaluation on the system and the results are encouraging.  相似文献

"物""我"的审美互动--"兴"之新解     

权雅宁 《南京师范大学文学院学报》2006,(2):67-72

“兴”的审美效果有高下之别。“兴”有不同的类型。兴是“诗缘情”理论的实践及发扬,是一种独特的生命省察方式,是中国古人混沌思维、巫术思维的具体体现。探讨兴的原始发生可以看到,最早的兴句可能是人对神的致敬、问候,是诗歌权力性质与一般口语的标志性区别之一。将“兴”规定为“物”“我”的审美互动可以具有普遍的解释功能。  相似文献
