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.
