Laboratory tests in the Stanford and Iranian cohorts.
| Stanford n (%) | Iran n (%) | p | |
|---|---|---|---|
| Raised ESR | 22 (42.3) | 69 (44.5) | 0.78 |
| Raised CRP | 22 (39.3) | NA | - |
| Proteinuria | 1 (1.8) | 2 (1.3) | 1 |
| Hematuria | 4 (7.1) | 18 (11.8) | 0.34 |
| HLA-B27 positive/tested (%) | 1/12 (8.3) | 7/159 (4.4) | 0.45 |
Groups were compared using Chi square test or Fischer’s Exact Test when appropriate. Patients with available data in the Stanford (total n= 56)/Iranian cohort (total n=163): ESR n=52/155, CRP n= 56/0, Proteinuria n=56/153, Hematuria n=56/153, HLA-B27 n=12/159.
