Note: For all three measures of physical function greater values are indicative of better function. SPPB values shown are the median (interval from the 25^th to the 75^th percentile). The sample size for walking speed is 5,769. Hyperuricemia: plasma urate level ≥ 7.0 mg/dL.

^aAmong participants with walking speed measured 5,182 were not diagnosed with gout and 587 participants were diagnosed with gout. 4,545 did not have hyperuricemia at visit 5 and 1224 did have hyperuricemia at visits 5.

^bAmong female participants with walking speed measured 3,105 were not diagnosed with gout and 236 participants were diagnosed with gout. 2,804 did not have hyperuricemia at visit 5 and 537 did have hyperuricemia at visits 5.

^cAmong male participants with walking speed measured 2,077 were not diagnosed with gout and 351 participants were diagnosed with gout. 1,741 did not have hyperuricemia at visit 5 and 687 did have hyperuricemia at visits 5.
