Table 3. Comparison of the iron deficiency/iron deficiency anaemia parameters between H. pylori-positive (n = 86) and negative (n = 225) children from Brazil, Chile and United Kingdom.
| Variables | H. pylori status | P value | |
| Negative(mean±SD) | Positive (mean±SD) | ||
| Serum ferritin (µg/L) | 41.6 (29.9) | 36.3 (23.5) | 0.06 |
| Transferrin saturation (%)* | 29.2 (11.0) | 28.3 (11.1) | 0.52 |
| Haemoglobin (g/L) | 130.6 (9.6) | 129.9 (10.9) | 0.57 |
| Haematocrit (L/L) | 0.39 (0.03) | 0.39 (0.03) | 0.57 |
| MCV (fL) | 83.8 (4.7) | 83.3 (5.0) | 0.48 |
| MCH (pg) | 28.2 (1.8) | 27.8 (1.9) | 0.09 |
*
obtained by dividing the serum iron concentration by the total iron binding capacity;
SD, standard deviation; MCV, mean corpuscular volume; MCH, mean corpuscular haemoglobin.
