A methotrexate dashboard: integrating MTXPK.org into the electronic health record to facilitate model-informed care for pediatric patients receiving high-dose methotrexate.
Article in JAMIA open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: The MTXPK.org webtool facilitates model-informed supportive care and glucarpidase use in patients receiving high-dose methotrexate, but its reliance on manual data entry limits workflow integration. We aimed to highlight how translational informatics can advance, automate, and enhance the usability of clinical decision support tools by embedding MTXPK.org within the electronic health record (EHR). Methods: A human factors study with 6 clinical providers guided iterative prototype development. MTXPK.org was rebuilt within the EHR using a 3-tier architecture with Fast Healthcare Interoperability Resources-based data retrieval, automated pharmacokinetic modeling, and interactive visualization. Results: Two rounds of prototyping with task-based evaluations and contextual inquiry showed progressive improvements in information recognition and navigation. The final design achieved excellent usability, with a System Usability Scale score of 90.4 compared to 57 for the original MTXPK.org tool. The dashboard is now live, automating data entry and generating individualized pharmacokinetic profiles with interactive visualization. Conclusions: The Methotrexate Monitoring Tool is an integrated methotrexate dashboard that automates data entry, improves usability, and facilitates model-informed supportive care and glucarpidase use.
