## What is MedDiffTx?

MedDiffTx: Rheumatology puts rheumatology treatment guidelines side by side, so you can see in seconds where they agree, where they differ, and exactly what differs: dose, threshold, duration or population.

Built for rheumatologists, rheumatology fellows, internists and pharmacists who need the answer at the bedside.

COMPARE GUIDELINES
• Compare view merges the guidelines by clinical scenario, each marked Agree, Differ (with what differs) or covered by one guideline only
• Each guideline on its own as a collapsible decision tree in its own structure
• Key points at the top of every view
• Redrawn treatment algorithms and tables
