研究如下:

結論是Omicron和Delta住院率並沒顯著不同。但我看到兩者住院數據如下(15063 vs 24)。總感染人數(208947 vs 15087) 住院率為(0.67% vs 0.16%)。Delta是Omicron 4 倍。Significant Test也表明Significant different。為何英國皇家學院說沒有顯著不同。不敢相信他們會犯如此簡單錯誤。請懂統計的幫忙驗證一下。
Hospitalisation and asymptomatic infection indicators were not significantly associated with Omicron infection, suggesting at most limited changes in severity compared with Delta.
