Table 5 Mean thickness of synovium and mean count of color Doppler pixels in the perisynovial regions of joints of patients from Canada and China centers according to origin of ultrasound operators and patients’ data

From: A semiquantitative color Doppler ultrasound scoring system for evaluation of synovitis in joints of patients with blood-induced arthropathy

Origin of ultrasound operators Origin of patients’ data Mean thickness of synovium (mm) - gray-scale US p value (between values according to origin of patients’ data) Mean count of color Doppler pixels p value (between values according to origin of patients’ data)
Canada Canada 2.1 P < 0.0001 930 P = 0.003
Canada China 4.1   3,633  
China Canada 2.0 P < 0.0001 868 P = 0.002
China China 3.9   3,796  
  1. Single layer synovium was considered in the data analysis
  2. Color Doppler pixel count was used as an outcome of synovial vascularity
  3. US, ultrasound. p values < 0.05 were considered statistically significant
