Intention-to-Treat Analysis
ITT定義
A statistical analysis method in clinical trials that includes all randomized participants in their originally assigned groups, regardless of whether they completed the treatment or adhered to the protocol. ITT preserves the benefits of randomization and reflects real-world conditions.
