Narrative reanalysis: A methodological framework for a new brand of reviews

In response to the evolving needs of knowledge synthesis, this manuscript introduces the concept of narrative reanalysis, a method that refines data from initial reviews, such as systematic and reviews, to focus on specific sub-phenomena. Unlike traditional narrative reviews, which lack the methodological rigor of systematic reviews and are broader in scope, our methodological framework for narrative reanalysis applies a structured, systematic framework to the interpretation of existing data. This approach enables a focused investigation of nuanced topics within a broader dataset, enhancing understanding and generating new insights. We detail a five-stage methodological framework that guides the narrative reanalysis process: (1) retrieval of an initial review, (2) identification and justification of a sub-phenomenon, (3) expanded search, selection, and extraction of data, (4) reanalyzing the sub-phenomenon, and (5) writing the report. The proposed framework aims to standardize narrative reanalysis, advocating for its use in academic and research settings to foster more rigorous and insightful literature reviews. This approach bridges the methodological gap between narrative and systematic reviews, offering a valuable tool for researchers to explore detailed aspects of broader topics without the extensive resources required for systematic reviews.
