* Detsky score is designed to evaluate the quality of a randomized clinical trial (maximum score 21); †quasirandomized controlled trials were considered as partial randomization (ie, patients are allocated according to known characteristics such as date of birth, hospital chart number, or day of presentation); ITT = intention-to-treat; N/A = not available.
