AI Article Synopsis
- The study involved 253 patients with rheumatoid arthritis, 177 with osteoarthritis, and 104 healthy individuals to evaluate the rheumatoid factor through five different serum tests.
- The results were analyzed using various biometric methods to identify common patterns and assess the diagnostic value of the tests for the respective diseases.
- The findings indicated variability in the results across the tests for the same diagnoses, suggesting that while some tests show high correlations, they are not entirely equivalent.
Article Abstract
The research has been executed on a sample embracing 253 patients affected with rheumatid arthritis (ARA criteria), 177 patients affected with osteoarthritis and 104 healthy subjects forming the standard sample. On the serum of every subject we have used a series of five different tests in order to find the rheumatoid factor. The results we obtained have been weighed with biometrical criteria of various kinds in order to single out any possible common behaviour-pattern and to determine the tests diagnostic value as regards the considered disease. We have noticed a different result of single tests as regards the same diagnosis so we can exclude an absolute equivalence of the five tests, though for some of them there is a high mutual relation.
