Patients with gout(n = 78 1st MTPJs) | Disease control(n = 28 1st MTPJs) | Healthy control(n = 16 1st MTPJs) | |
---|---|---|---|
HRUS, high-resolution ultrasound; MTPJ, metatarsophalangeal joint. | |||
Results are expressed as number (%) of MTPJs. | |||
Test of proportions. *p<0.05. and †p<0.01 compared with patients having gout. | |||
The proportion of MTPJs in patients with gout showing HRUS evidence of erosions, tophus-like lesions and double contour was significantly greater than in the disease or healthy control groups. | |||
