Charting the data
According to the methodological framework of Arksey and O’Malley, charting the data and collating the results are iterative and narrative processes: “A ’narrative review’ or ’descriptive analytical’ method is used to extract contextual or process oriented information from each study.”11 For this scoping review, it was first searched for characteristics of the included body of literature, and then for the main characteristics of prenatal counseling for extreme prematurity at the limit of viability. Data was charted from the included studies using a data extraction tool developed by the reviewers. The tool included data about the authors, the year of publication, the journal, the study design, the country in which the study was conducted, the objective of the study, and the result or conclusion of the study. Two researchers (LDP, EJTV) discussed the extracted data and categorized the data for further analysis.
