@JCooper93488061 @davidwdowdy @ContractJames @NEJM ARR has a time factor. If the added protection lasts a long time, the absolute risk reduction increases dramatically over what is seen in a short study. There was no sign of waning against severe disease during six weeks.
@JCooper93488061@davidwdowdy@ContractJames@NEJM ARR有一个时间因素。如果增加的保护持续很长时间，绝对风险降低会比短期研究中所见的显著增加。在六周内，没有迹象表明对抗严重疾病的能力有所减弱。
