Top-N Institutions

Ranks institutions by paper count. Toggle between Papers and Citations. Hover for full details.

Top-N Authors

Ranks individual authors by paper count or total citations. Toggle between metrics using the buttons above the chart.

Degree Distribution

Degree = number of distinct co-authors a researcher has in this literature. Count = number of researchers with that many co-authors. Most authors collaborate with only a few others (low degree); a small number are highly connected hubs (high degree). The log–log panel reveals whether the distribution follows a power law, which is typical of real collaboration networks.

Co-authorship Network

Each node is an author; an edge connects two authors who share at least one paper. Degree (node size) = number of distinct co-authors. Colour = Louvain community (research cluster detected by modularity optimisation). Click a community in the legend to isolate it.

Degree vs Betweenness Centrality

Degree (x-axis) = number of distinct co-authors — a measure of direct connectivity. Betweenness centrality (y-axis) = fraction of shortest paths between all other author pairs that pass through this author — a measure of brokerage between research groups. Point size reflects total papers; colour reflects community.

Country Collaboration Heatmap

Co-authored papers between top country pairs. Darker = more collaboration.

Author Citation Impact

Papers (x) vs total citations (y), both on log scales.

Citations by Community

Total citations per Louvain community. Hover for papers and cit/paper.

Country Output vs Impact

Left: paper count. Right: citations per paper.

Top Funders

Paper count per funder (OpenAlex funding coverage is partial — treat as lower bounds).

Funding Coverage by Country

% papers acknowledging funding (left) and funded vs no-record stacked counts (right).

Departments (experimental)

⚠ Experimental — partial coverage. Department names extracted heuristically from author affiliation strings.

Publications per Year

Annual paper count with linear regression trend line.

Country Trends Over Time

Annual output for the top 8 countries.

Network Growth Over Time

Cumulative authors (blue, left axis) and collaborations (red, right axis).

Author Position Analysis

Top-left: stacked bar showing each prolific author's papers by position: first (blue), last (green), middle (orange). Top-right: same data as 100% proportions. Bottom-left: each point is an author with ≥5 papers. X-axis = total papers; y-axis = middle-author rate (proportion of papers where the author is neither first nor last). A high middle-author rate indicates participation in many collaborations without leading them. The dashed line marks 0.70 as a reference threshold. Bottom-right: top-20 first-authors and top-20 last-authors.

§12a Study Type Distribution

Overall breakdown by study design. MeSH publication-type tags take priority; title keywords are used when MeSH is absent. Other = unclassifiable with current data.

§12b Study Types Over Time

Annual paper counts stacked by study design (2000–2024).

§12c Study Type Mix by Country

100 % stacked bar: each country's papers broken down by study design. Compare the RCT share across high-output countries.

§12d Study Type Network

Co-authorship network coloured and shaped by each author's dominant study type. Click legend entries to isolate a study type. Shapes: ● Observational · ◆ SR/MA · ■ Review · ▲ RCT · ✚ Clinical Trial · ○ Other.
