  1. Samples of joint fluid were collected from the knees. Joints affected by rheumatoid arthritis (RA) and those affected by osteoarthritis (OA) are seen as being comparable. The measurement of viscosity is done in Pascal seconds, whereas consistency is done in (s). The rate index does not have any units. The authors indicated that more than 200 samples were investigated in total, however, they did not specify the number of samples that were included in each category7,14,20,22.
