  1. Data are presented as n (%) or median (IQR) or mean (SD). All P values less than 0.05 were considered significant. Group 1: Women with primary PPH. Group 2: Women without primary PPH. IQR: Inter-quartile range. n: Number. Mod: Moderate. Sev: Severe. Hb: Haemoglobin. G6PD: Glucose-6-Phosphate Dehydrogenase. HCT: Haematocrit. MCV: Mean Cell Volume. MCH: Mean cell haemoglobin. MCHC: Mean Corpuscular Haemoglobin Concentration. PLT: Platelets
