NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
GBD Analysis Suite: An Open-Source R Shiny Dashboard for Multi-Method Burden of Disease Research
ABSTRACT
Background:
The Global Burden of Disease (GBD) study provides the most comprehensive cross-national burden estimates available, but translating GBD data downloads into publication-ready analyses requires an integrated, multi-method workflow spanning trend estimation, changepoint detection, demographic decomposition, forecasting, frontier benchmarking, and health inequality measurement. Existing tools cover portions of this workflow but none integrates it end to end in a code-free interface, creating a disproportionate barrier for investigators in resource-limited settings.
Objective:
To develop and release an open-source R Shiny dashboard, the GBD Analysis Suite, that integrates the 11 analytical modules required for a standard GBD burden of disease study into a single user-uploadable, code-free web interface, and to describe its architecture, methodology, and intended use.
Methods:
The application was built using R 4.5.3 and the Shiny framework, integrating established statistical packages (forecast, segmented, openxlsx, ggplot2, plotly, and others) into 11 modules covering data import, choropleth mapping, estimated annual percentage change (EAPC), joinpoint regression, Kitagawa and Das Gupta decomposition, multi-model time-series forecasting, descriptive visualization, Socio-demographic Index (SDI) based frontier analysis, age period cohort (APC) visualization, slope and relative index of inequality (SII and RII), and batch export. The application accepts any GHDx-formatted CSV or Excel file, auto-detects standard column names, and enforces internal consistency by construction. Kitagawa decomposition uses the symmetric mid-point formulation to guarantee exact additivity, and all forecast models use Box-Cox log transformation with bias-corrected back-transformation to guarantee non-negative point estimates and prediction intervals.
Results:
The application is deployed at https://bela2003.shinyapps.io/GBD-Analysis-Suite/ and runs in any modern web browser without local installation. On the bundled 204-country, 34-year demonstration dataset, a complete batch export (an 8-sheet Excel workbook plus 10 or more figures) completes in approximately 90 seconds at a peak memory footprint of approximately 800 MB. A feature comparison against five existing tools (GBD Compare, GBD Foresight, NCI Joinpoint, BAPC, NordPred) across 14 capability dimensions shows that the GBD Analysis Suite is the only reviewed platform combining user-uploaded data input with code-free access to all six core analytical methods of modern GBD papers. Source code is publicly available at https://github.com/levai-2003/GBD-Analysis-Suite under the MIT license.
Conclusions:
The GBD Analysis Suite lowers the technical barrier to reproducible, multi-method burden of disease analyses. It is designed particularly for researchers in low- and middle-income countries where biostatistical support, commercial software licenses, and high-performance computing are often unavailable. The modular design imposes no structural limitations on disease area, geography, or time window.
