Laboratory test results of the participants
| Parameter | Patients Mean ± SD | Control group Mean ± SD | P-value |
|---|---|---|---|
| Vitamin B12 [pg/ml] | 291 ±233 | 330 ±247 | 0.18 |
| Folate [ng/ml] | 5.97 ±1.92 | 6.07 ±2.29 | 0.87 |
| TSH [µIU/ml] | 1.32 ±0.96 | 1.56 ±1.18 | 0.10 |
| Zinc [µg/dl] | 84.90 ±21.80 | 88.50 ±23.10 | 0.41 |
| Ferritin [ng/ml] | 14.72 ±10.70 | 25.30 ±14.41 | < 0.001 |
| 25(OH)D [ng/ml] | 14.03 ±8.09 | 17.01 ±8.59 | 0.01 |
SD – standard deviation, TSH – thyroid stimulating hormone, 25(OH)D – 25-hydroxyvitamin D. Serum vitamin B12, folate, TSH and zinc levels were similar in patients and healthy individuals. However, serum ferritin and 25(OH)D levels were significantly lower in patients when compared with the control group.
