Flow chart of study selection process. PubMed, Embase, CNKI, Wanfang and Weipu were searched. The search terms were ‘sepsis’ and ‘resveratrol’. A total of 208 articles were included. Another 52 articles were obtained that met the requirements by searching the references of related articles. Of the 260 articles identified, 89 were duplicated. By reading the title and abstract, another 113 articles were excluded: 51 articles were not relevant, 39 articles were a review, 21 articles were a conference, 1 was an editorial and 1 was a chapter article. There were 58 articles left. Then through review of the full text, 47 articles were found to have no specific values for the outcome indicators for meta-analysis. Finally, articles containing at least one outcome indicator were included, amounting to 11 articles.
