limitations

Are there limitations due to study design?

Yes, different study designs come with inherent limitations. Cross-sectional studies can only provide a snapshot in time and cannot establish causality. Case-control studies are prone to recall bias and selection bias. Although cohort studies are generally stronger, they can be expensive and time-consuming to conduct. Randomized controlled trials (RCTs) are the gold standard but may lack generalizability to the broader population.
