iteration?

We used the World Health Organization (WHO) definition of severe and critical COVID-19 (Table 1). We used similar methodology to the first iteration of the SSC COVID-19 guidelines, but we formally used the evidence to decision (EtD) framework to generate recommendations (3). More details about the methods can be found in the Supplement and Figures S1-S3 (http://links.lww.com/CCM/G188). Detailed evidence profiles and evidence to decision tables are presented in Tables S1-S23 (http://links.lww.com/CCM/G188). We present the updated guidelines’ statements and recommendations in Table 2 and the complete list of recommendations in Table 3.

我们使用了世界卫生组织（WHO）对严重和危重COVID-19的定义（表1），也重复使用了与SSC COVID-19第一次指南相似的方法，但我们正式使用了决策证据（EtD）框架来生成建议（3）。关于方法的更多详细信息见附录和图S1-S3（http://links.lww.com/CCM/G188）。详细的证据概况和决策表证据见表S1-S23（http://links.lww.com/CCM/G188）。我们在表2中列出了更新的指南声明和建议，在表3中列出了完整的建议列表。
