Figure 2
A combined bar and line graph displays the temporal distribution and methodological profile of identified reviews published per year from 2013 to 2025. The x-axis represents the years from 2013 to 2025, and the y-axis represents the number of reviews, ranging from 0 to 12. The graph includes four types of reviews: scoping reviews, qualitative systematic reviews, mapping reviews/systematic maps, and meta-analyses, each represented by different colored bars. The purple line indicates the total number of reviews per year. Key data points include a steady increase in the total number of reviews from 2018, peaking at 10 in 2023, followed by a decline to 4 by 2025. Scoping reviews show a notable increase starting in 2019, while qualitative systematic reviews and meta-analyses also contribute to the overall trend.Temporal distribution and methodological profile of the identified reviews.
