In lupus nephritis (LN), “activity” gets the spotlight—but chronic scarring often decides the long game. So: which chronicity score best predicts outcomes—NIH Chronicity Index (NIH-CI) or the Mayo Clinic Chronicity Score (MCCS)?

Bottom line: MCCS and NIH-CI are comparable and add prognostic signal beyond clinical data—with IF/TA doing most of the heavy lifting—and performance was consistent in Class V LN. MCCS may offer a practical edge by aligning chronicity grading across glomerular diseases.
