Visit Schedules and Longitudinal Data Collection

Visit schedules and longitudinal data collection are essential components of clinical research that organize when study data are collected and how repeated observations are managed throughout the trial. Visit schedules define when study assessments should be performed, while longitudinal data collection involves collecting the same clinical measurements from participants at multiple time points. Together, they form a critical foundation for CRF design, database development, study monitoring, and the generation of high-quality, analysis-ready clinical research data.
