Comparative analysis of instruments measuring peripheral arthritis activity in Spondyloarthritis: a measurement properties study in 13 RCTs.

ABSTRACT:

Objectives

Using randomised controlled trial (RCT) data, this study evaluated the measurement properties of selected instruments to assess peripheral arthritis in axial and peripheral spondyloarthritis (axSpA/pSpA) and to inform selection of the best-performing instrument.

Methods

Eligible studies were RCTs in axSpA or pSpA with individual patient data available to calculate Patient Global Assessment (PGA), swollen/tender joint counts (44 or 66/68 joints), C reactive protein, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Axial Spondyloarthritis Disease Activity Score, Disease Activity Index for Psoriatic Arthritis/Disease Activity in Psoriatic Arthritis with 44 joint count (DAPSA44) and 44-joint Disease Activity Score at baseline and timing of primary endpoint
