Disadvantages: reliance on recall or records to determine exposure status; Throughout the process, the researcher has less control over variables. When searching for evidence-based information, one should select the highest level of evidence possiblesystematic reviews or meta-analysis. In other words, quantitative and qualitative observation helps the researcher to gather the information that would later be analyzed in order to come up with research findings. It can identify the causal factors for these changes and their long-term impact. Select a sub-classification of the cohortthe unexposed control cohortto be the comparison group. In this kind of study, the research focuses on participant observation, where the researcher becomes an active participant in that culture to understand its experiences.
