The role of metrology in axSpA: does it provide unique information in assessing patients and predicting outcome? Results from the BSRBR-AS registry.

BASMI was estimated moderately well by other routinely measured factors in patients with axSpA and was an independent predictor of response to biologic therapy for some, but not all, commonly used measures. Consensus around its role in disease monitoring and clinical decisions, particularly in the likely context of face to face consultations becoming less frequent, remains to be established.
