简介
Objective
To develop and validate classification criteria for microscopic polyangiitis (MPA).
Methods
Patients with vasculitis or comparator diseases were recruited into an international cohort. The study proceeded in 5 phases: 1) identification of candidate items using consensus methodology, 2) prospective collection of candidate items present at the time of diagnosis, 3) datadriven reduction of the number of candidate items, 4) expert panel review of cases to define the reference diagnosis, and 5) derivation of a pointsbased risk score for disease classification in a development set using least absolute shrinkage and selection operator logistic regression, with subsequent validation of performance characteristics in an independent set of cases and comparators.
Results
The development set for MPA consisted of 149 cases of MPA and 408 comparators. The validation set consisted of an additional 142 cases of …
