n: Number of observed subjects in each group;
a: Haemotological reference parameters according to French Society of
haematology [21,52];
b: for these two haematological parameters, the reference values were defined
according to the stage of pregnancy to obtain prevalences of types’ anaemia
and hemodilution; hemoglobin levels are similar in the first and third trimesters of
pregnancy, it is the same for hematocrit. MCV: Mean corpuscular volume; MCH:
Mean corpuscular hemoglobin; HMA: Hypochromic Microcytic Anaemia; HNA:
Hypochromic Normocytic Anaemia; NNA: Normochromic Normocytic Anaemia;
NMA: Normochromic Microcytic Anaemia; S: Difference statistically significant for p
< 0.05; NS: Difference not statistically significant for p > 0.05 |
