There was a mistake in Figure 1 as published. The Figure 1 part label images C & D were missing. The corrected figure and its caption appear below.
Figure 1. Effects of iron supplements on the fertility of pregnant anemia rats. (A, C) Physiological pregnancy anemia model. (B, D) Pregnancy anemia model after IDA. Compared with the physiological pregnancy group, *P < 0.05; **P < 0.01.
There was a mistake in Figure 2 as published. The Figure 2 part label images C and D were missing. The corrected figure and its caption appear below.
Figure 2. Effect of iron supplements on the number of embryos in pregnant anemic rats. (A, C) Physiological pregnancy anemia model. (B, D) Pregnancy anemia model after IDA. Compared with the physiological pregnancy group, **P < 0.01.
There was a mistake in Figure 3 as published. In Figures 3C, D images, the symbol “#” should have been used in the pregnancy anemia model after IDA. The corrected Figure 3 appears below.
Figure 3. Effects of iron supplements on embryo and offspring development in pregnant anemia rats. (A, B) Physiological pregnancy anemia model. (C, D) Pregnancy anemia model after IDA. Compared with the physiological pregnancy group, *P < 0.05; compared with the IDA pregnancy group, #P < 0.05; ##P < 0.01.
There was a mistake in Figure 6 as published. In Figures 6C, D images, the symbol “#” should have been used in the pregnancy anemia model after IDA. The corrected Figure 6 appears below.
Figure 6. Effects of GD20 iron supplement on serum iron-related indicators in pregnant anemia rats. (A, B) Physiological pregnancy anemia model. (C, D) Pregnancy anemia model after IDA. Compared with the physiological pregnancy group, *P < 0.05; **P < 0.01. Compared with the IDA pregnancy group, #P < 0.05; ##P < 0.01.
There was a mistake in Figure 7 as published. In Figure 7B image, the symbol “#” should have been used in the pregnancy anemia model after IDA. The corrected Figure 7 appears below.
Figure 7. Effect of GD20 iron supplement on tissue iron content in pregnant anemic rats. (A) Physiological pregnancy anemia model. (B) Pregnancy anemia model after IDA. Compared with the physiological pregnancy group, *P < 0.05; **P < 0.01. Compared with the IDA pregnancy group, #P < 0.05; ##P < 0.01.
There was a mistake in Figure 8 as published. In Figure 8D, CPXI on the vertical axis should be GPX1. The corrected Figure 8 appears below.
