Crowe's Classification

Crowe's Classification一直很難記，尤其是在臨床應用時。重點在於A/B之比值，才能對應至subluxation的百分比。
A: head-neck junction至tear drop之參考線之高度
B: Pelvic height

Group	Description
I	Subluxation < 50% or proximal dislocation < 0.1 (10%) of the pelvic height
II	Subluxation 50%–75% or proximal dislocation of 0.1 to 0.15 (10% to 15%) of pelvic height
III	Subluxation 75%–100% or proximal dislocation of 0.15 to 0.20 (15% to 20%) of pelvic height
IV	Subluxation > 100% or proximal dislocation of > 0.20 (20%) of pelvic height

統計、流病、EBM 9: ABC of Epidemiology

當初在上課時，在同學的介紹之下發現了在 Kidney International 連載的文章 ABC of Epidemiology，也是橫跨三年的文章。他人之石可以攻錯，好文章分享。統計與流病是相輔相成的，正如Sir William Osler所說的"He who studies medicine without books sails an uncharted sea, but he who studies medicine without patients does not go to sea at all."
