Dalbeth et al, 2007³⁹	Prospective clinical cohort in unselected rheumatology patient clinic	20 participants with initial baseline assessment; hand function assessed on Sollerman hand function test, DASH instrument, fingertip to palm distance, and grip strength; number of tophi on hands counted and position recorded	Data were analyzed cross-sectionally, both univariate and multiple linear regression	Number of joints with tophi was the best predictor of the Sollerman hand function in both univariate analyses (r² = 0.59) and multivariate analyses (F = 3.94, r² = 0.81, P = 0.024); hand tophus joint count also correlated with hand disability on the DASH instrument (r = 0.77, P < 0.0001); tophus counts and flares correlated over prior 6 months (r = 0.63, P < 0.003)
