文法句型

open-label + trial / study / extension

用法筆記

Almost always used before a noun such as 'trial', 'study', 'design', or 'extension'. Contrasts with 'blinded' and 'double-blind' studies, where one or both sides do not know which treatment is being given.

常見錯誤

❌The trial was open-label to the patients.
✅The trial was open-label, so the patients knew which drug they were taking.
💡'open-label' is not used with 'to'; it describes the whole study, not a relationship between people.
