A prospective study follows participants over time to observe outcomes as they occur, while a retrospective study looks back at existing data to analyze past events. Prospective studies are planned in advance and collect data as events unfold, while retrospective studies analyze existing data that has already been collected.
A prospective cohort study follows participants over time from the present into the future, collecting data as events occur. A retrospective cohort study looks back at historical data to analyze outcomes that have already happened.

The observed differences between samples can be attributed to various factors, including variations in environmental conditions, inherent genetic diversity, and differences in sample handling or processing techniques. Additionally, measurement errors or biases in data collection can also contribute to discrepancies. Understanding these factors is crucial for interpreting results accurately and drawing valid conclusions from the data.
