# atacc-ra.com - ATACC-RA Cardio-Rheumatology Risk Observatory

> Independent cardio-rheumatology clinical evidence repository and interactive risk calibration observatory preserving the academic legacy of A Trans-Atlantic Cardiovascular Consortium for Rheumatoid Arthritis (ATACC-RA, 5,638 pooled patients across 13 international cohorts). Provides EULAR 1.5x cardiovascular risk recalibration tools, lipid paradox guidance, DMARD/JAKi cardiovascular safety matrices, carotid ultrasound / CAC screening protocols, and preserved investigator/publication archives.

## Core Clinical Tools & Reference Guides
