A Rapid Review and Meta-Analysis of the Asymptomatic Proportion of PCR-Confirmed SARS-CoV-2 Infections in Community Settings

Meta-analysis dataset for the following article: A Rapid Review and Meta-Analysis of the Asymptomatic Proportion of PCR-Confirmed SARS-CoV-2 Infections in Community Settings.<br>These CSV format data enable the calculation of a pooled asymptomatic proportion of PCR-confirmed COVID-19 cases based on available studies (n=21) with methodologically-appropriate design to detect and identify truly asymptomatic cases. The asymptomatic proportion is given as the number of asymptomatic PCR-confirmed infections over the total number of PCR-confirmed infections.<br>The file also includes the completed PRISMA checklist for this review.

本元分析数据集对应下述研究文章：《社区环境中经聚合酶链式反应（Polymerase Chain Reaction，PCR）确诊的严重急性呼吸综合征冠状病毒2型（Severe Acute Respiratory Syndrome Coronavirus 2, SARS-CoV-2）感染无症状占比快速回顾与元分析》。
本数据集采用CSV格式，可基于21项采用方法学严谨设计的现有研究，计算经PCR确诊的新型冠状病毒肺炎（Corona Virus Disease 2019，COVID-19）病例的合并无症状感染占比，此类研究可精准检测并识别真正的无症状感染者。
无症状感染占比的计算方式为：经PCR确诊的无症状感染人数除以经PCR确诊的感染总人数。
本数据集文件还包含本次回顾研究已完整填写的系统评价与元分析首选报告条目（Preferred Reporting Items for Systematic Reviews and Meta-Analyses, PRISMA）检查表。
