However, HPT disorders (p = 0.0043), chronic HPT (p = 0.0003), mean Hb (g/dl) (p = 0.0409), and anemia (p = 0.0381) were significantly different between the pregnant women with a BMI of ≥25.0 kg/m2 compared to the pregnant women with a BMI of <25 kg/m2. The gene discussed is GSTM1; the disease is anemia (phenotype).
