“…Among studies without data on correlation coefficients, 10 , 29 , 32 , 34 , 35 , 37 , 38 , 41 , 42 , 43 , 45 , 47 , 48 , 51 , 52 , 55 , 58 , 59 , 60 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 we focused on those that reported the concentrations of both hepcidin and hemoglobin across 2 or 3 trimesters. 10 , 34 , 35 , 41 , 43 , 51 , 58 In some of these studies, hemoglobin concentrations increased with increasing hepcidin concentrations as gestation advanced, 35 , 51 whereas in others, hemoglobin concentrations decreased in tandem with decreasing hepcidin levels across gestation.…”
