What characterizes a retrospective study?

• A. It analyzes forward-looking data
• B. It assesses the impact of interventions
• C. It looks backward to examine past conditions
• D. It is commonly focused on cross-sectional data

Answer: (C)

A retrospective study is characterized by its focus on looking backward to examine past conditions or events. This type of study often involves reviewing existing records or data to investigate outcomes or associations that have already occurred. Researchers collect data about participants' past exposures or experiences and then assess how these relate to current outcomes. This method allows for the exploration of potential correlations and can help generate hypotheses for further research. The other options do not accurately describe a retrospective study. Analyzing forward-looking data pertains more to prospective studies, which track participants moving forward in time. Assessing the impact of interventions is typically associated with experimental or interventional studies rather than retrospective ones. Lastly, while some retrospective studies may involve cross-sectional elements, the defining characteristic is not primarily focused on cross-sectional data. Instead, retrospective studies are distinctive for their backward-looking approach to understanding relationships between past events and current conditions.
