A systematic review is best characterized as a qualitative pooled study synthesizing various research findings. This type of review is designed to comprehensively search for, evaluate, and synthesize all relevant studies on a particular topic. It employs a rigorous methodology to minimize bias and provides a clear overview of the existing evidence. By critically appraising the studies included, a systematic review can identify patterns, discrepancies, and areas needing further research, thereby offering insights that can inform clinical practices and guidelines.

In contrast to the other options, a systematic review does not center around a single study, nor does it focus on individual patient cases or comparisons of experimental treatments. It aggregates findings from multiple sources to present an evidence-based assessment, which is essential in fields such as medicine and healthcare where treatment options and methodologies are continuously evolving based on research.
