- 📌 Code Requirements & Notes
- 📂 Dataset Version
- All scripts require the ABCD 6.0 data release.
- 📚 Medication Categories
- You can explore the medication categories at the following resources:
- 🔹 Interactive Tableau Dashboard
- 👉 https://public.tableau.com/views/ABCD_Medications_v1/MedicationDashboard
- 🔹 Methodology Preprint (medRxiv)
- 👉 https://www.medrxiv.org/content/10.1101/2025.11.19.25340321v1
- 🗂️ Mapping File
- To reproduce the medication category definitions used in the Tableau dashboard, users should rely on the following two files in this repository:
- ABCD_Medication_Mapping_Github.xlsx
- Mapping_2wk_Med_Use
- These files contain the full medication mapping logic and category assignments used to generate the dashboard-level summaries, including harmonized medication groupings derived from ABCD medication variables.
- Users attempting to reproduce, extend, or audit the Tableau dashboard should use these files as the primary reference for medication classification.
- If you have any questions, concerns, or encounter issues when using these files, please feel free to reach out to [email hidden]
- .
- If you use this mapping framework in your work, please cite the following preprint:
- Lopez, D. A., et al. [Title]. medRxiv (2025).
- https://www.medrxiv.org/content/10.1101/2025.11.19.25340321v1
- 📄 Data Format
- Scripts assume the ABCD dataset is in long format:
- One row per participant per visit
- All medication survey items exist within that row
- 💻 Programming Language
- All scripts are written in R.
- 🏷️ Generated Variables
- For each category in the medication mapping file, the scripts generate three binary indicator variables:
- Variable Prefix Timeframe Notes
- x1yr_ Past year Only collected starting in Year 3
- x2wk_ Past 2 weeks Available at all visits
- x24hr_ Past 24 hours Available at all visits
- Each variable is coded:
- 1 → medication from that category was taken
- 0 → not taken
- ⚠️ Missing Data
- All NA values in generated variables are recoded to 0, meaning “did not take medication.”

The paper's code and data availability statement is in the Data section.
Tracing map
Proposed by the machine: these links were found in the paper and verified at the source, without human review. The map will receive a Zenodo DOI once one of the paper's authors has validated it with their ORCID.
What the map holds:
- 1 repository of the authors' code, each at its verified commit, with its license and how the link was found in the paper;
- 0 scripts, each with its path and the digest of its content;
- no match between paragraphs and code yet;
- neither the text of the paper nor the code itself.
Its JSON (tracing-map.json) is deposited on Zenodo with its DOI once the map is validated.
Data
No dataset and no data link were found in the paper.
Code and data availability statement
The paper has a code and data availability statement. Its license (CC BY-NC-ND) does not allow reproducing it here; in short, from what the harvester recognized in it:
- it points to the authors' code: Daniel-Adan-Lopez/
ABCD_Medications
Read it in the paper: doi.org/10.1038/s41598-026-50046-8.
Versions
The history of this record: each version stored by the harvester or made by a correction of its authors or of the maintainers of its code, and what changed in its facts. The texts of the paper (its abstract, its availability statements) are not part of it; versions that changed only those are not listed.
