Comparison of the Laboratory Test Results
A statistically significant difference was determined only in the Hb
value, with the highest value determined in the SGA group (p=0.025). No
other statistically significant difference was observed between the
groups in respect of the other laboratory results. The lowest NLR was
observed in the SGA group. The highest PLR was observed in the SGA group
and the lowest PLR in the LGA group.
When maternal age and CBC variables were evaluated sepatrately, no
statistically signficant effect was determined on birthweight or
gestational age at birth (Table 1). In the multivariate linear
regression analysis, gestational age at birth was determined to be
associated with an increase in maternal Hb value and a decrease in PLR
(Table 2) while a decrease in Hb, PLR, and neutrophil count, and an
increase in BMI and NLR were each determined to be independent factors
for birthweight (Table 3).
In the comparison of term and preterm groups, the Hb value in the
preterm group was observed to be statistically significantly lower
(p=0.005). Although no statistically significant difference was observed
between the groups in respect of the other variables, the WBC, platelet,
RDW values and PLR were seen to be higher in the preterm group, and the
neutrophil, lymphocyte, PDW and MPV values were observed to be lower. No
difference was determined between the groups in respect of the NLR.
In the evaluation of the preterm subgroups, the Hb value was
statistically significantly lowest in the 35+0-36+6 gestational weeks
age age group, and the highest value was in the 31+0-32+6 gestational
weeks group (p=0.005). The statistically significantly highest RDW value
was observed in the 31+0-32+6 gestational weeks group (p=0.001). The
highest NLR was observed in the 35+0-36+6 gestational weeks group but
not at a statistically significant level (p=0.387). The highest PLR
value was observed in the 35+0-36+6 gestational weeks group but not at a
statistically significant level (p=0.118). No difference was observed
between the groups in respect of other CBC variables.
