原文也批評了該研究聲稱的Delta和Omicron住院率沒有明顯差別的說法。指出相差4倍。且統計上Significant。我計算

的住院率OR(Odds ratio)也差4倍。 The Imperial team, led by Professor Neil Ferguson, said there was little evidence to suggest that omicron was milder, in contrast to mounting real-world and laboratory data showing the opposite. Imperial’s own data, which looked at more than 200,000 cases between November 29 and December 11 also showed that the risk of needing hospital attention from omicron was 0.15 per cent compared to 0.66 per cent compared to delta – four times less.

所有跟帖： 

• 你用的是匯總的數據，他用的是回歸分析，兩者可以不一致。你仔細看數據，得O的年輕人的比重較高，而年輕人的住院率低，所以拉低了O的總 -skyline荷9- ♀ (553 bytes) () 12/20/2021 postreply 17:11:20

• 你算說到點子上了。我也有此猜疑。隻是原文隻提供了匯總數據。謝謝。 -value_hunter- ♂ (0 bytes) () 12/20/2021 postreply 17:20:59

• 這有點像田橫賽馬，有選擇性地比較，違背了統計最基本的原則 : 隨機原則。 -LingYuan- ♂ (0 bytes) () 12/20/2021 postreply 20:04:40

• 田忌賽馬。嗯，現在不少都是選擇性比較，統計也是，其結果會差很大甚至得出相悖結果。 -pickshell- ♀ (0 bytes) () 12/21/2021 postreply 06:17:53

• 他在混淆概念。同質之間的比較，怎麽算做上士對下士。誰做統計不分組？難道將孩子與老人比？ -fuz- ♂ (0 bytes) () 12/21/2021 postreply 10:31:40
