METHODS: We will conduct a systematic search for CPGs. Recommendations for nutritional supplementation with immunomodulatory substrates for individuals undergoing major oncological surgery will be analysed using the Appraisal of Guidelines Research and Evaluation-Recommendations Excellence tool. CPGs will be analysed using the Appraisal of Guidelines Research and Evaluation II tool. The SRs cited in the recommendations will be analysed using the A Measurement Tool to Assess Systematic Reviews II tool and additional questions regarding heterogeneity in reviews. The clinical trials cited in the SRs and in the guideline recommendations (when applicable) will be analysed according to questions regarding heterogeneity in trials. The results will be presented in tables or charts using descriptive analyses.
BACKGROUND: The results of this study will be disseminated through relevant conferences and peer-reviewed journals.

方法:我们将对CPG进行系统的搜索。将使用“评估指南研究和评估-推荐卓越”工具分析接受大型肿瘤手术的个体的免疫调节底物营养补充建议。将使用评估准则研究和评估II工具对CPG进行分析。建议中引用的SR将使用评估系统审查的衡量工具II工具和有关审查异质性的其他问题进行分析。SRs和指南建议(适用时)中引用的临床试验将根据有关试验异质性的问题进行分析。结果将使用描述性分析在表格或图表中呈现。
背景:这项研究的结果将通过相关会议和同行评审的期刊进行传播。
