Material and Method
A retrospective scan was made of the data of 15000 women who gave birth at Kayseri Research and Training Hospital between May 2018 and December 2019. The patients included in the study were those aged 18-40 years, with a singleton pregnancy, with no systemic disease in the obstetric history, and who were not taking any vitamins, iron preparates or other medication for any reason. Patients with multiple pregnancies or any congenital anomalies were excluded from the study.
Approval for the study was granted by the Ethics Committee of Erciyes University. Informed consent for participation in the study was obtained from all the participants. All the study procedures were applied in compliance with the Helsinki Declaration.
The complete blood count (CBC) values taken from the patients at least 1 month before the birth were used in the study and the CBC values immediately before or after birth were not used. A record was made for each patient of maternal age, weight and BMI, gravida, parity, number of abortus, infant gender and birthweight, and the FBC variables of Hb, neutrophils, lymphocytes, NLR, platelets, PLR, PDW, RDW-sd and MPV values.
