英国皇家学院关于Omicron的研究结论是否有错。懂统计的帮忙验证一下。

研究如下：

结论是Omicron和Delta住院率并没显著不同。但我看到两者住院数据如下（15063 vs 24）。总感染人数（208947 vs 15087) 住院率为（0.67% vs 0.16%）。Delta是Omicron 4 倍。Significant Test也表明Significant different。为何英国皇家学院说没有显著不同。不敢相信他们会犯如此简单错误。请懂统计的帮忙验证一下。

Hospitalisation and asymptomatic infection indicators were not significantly associated with Omicron infection, suggesting at most limited changes in severity compared with Delta.
