====== Comparative Assessment ====== **Definition:** A *comparative assessment* is a structured evaluation that directly compares two or more methods, interventions, or entities to determine their relative advantages, disadvantages, and outcomes. **Key Elements:** * **Multiple comparators**: e.g., treatments, devices, or strategies. * **Defined evaluation criteria**: such as effectiveness, safety, cost, usability, or efficiency. * **Systematic methodology**: may include randomized trials, observational studies, or meta-analyses. * **Goal**: to establish which option performs better or is more appropriate under specific conditions. **Example (Medical Context):** A comparative assessment between **stereoelectroencephalography (SEEG)** and **subdural electrodes (SDE)** aims to determine which technique more effectively localizes seizure onset zones, has fewer complications, and leads to better surgical outcomes. **Related Tags:** [[evidence-based medicine]], [[meta-analysis]], [[comparative effectiveness research]], [[clinical decision-making]]
