Consistent follow-up is essential for several reasons:
1. Data Accuracy: Regular intervals help maintain the accuracy of data by reducing recall bias and ensuring the timely capture of changes in exposure or outcome status. 2. Study Validity: Appropriate follow-up intervals can enhance the internal validity of a study by reducing loss to follow-up and its associated biases. 3. Outcome Detection: Timely follow-ups are crucial for detecting changes in health outcomes, especially in studies investigating chronic diseases or long-term exposures.
