Time and Cost: Conducting a study over many years is both time-consuming and expensive, often requiring substantial funding and resources. Participant Retention: Maintaining participant involvement over long periods can be difficult, leading to potential attrition bias. Confounding Variables: Over time, various confounding factors may influence the observed outcomes, complicating the analysis.
