Several factors are assessed to ensure compatibility:
Study Design: Different study designs, such as cohort studies and case-control studies, need to be comparable in terms of their objectives and methodologies. Population: The populations studied should be similar in terms of demographics, geography, and other relevant factors. Measurement Methods: The tools and techniques used to measure exposures and outcomes should be consistent and validated. Data Quality: The completeness, accuracy, and reliability of the data should be evaluated.
