Corrigendum: Prevalence of iron-deficiency anemia in pregnant women with various thalassemia genotypes: thoughts on iron supplementation in pregnant women with thalassemia genes

In the published article, there was an error in the name and abbreviation of the measure “mean corpuscular hemoglobin concentration” abbreviated to “MCHC”. It should be “mean corpuscular hemoglobin” and abbreviated to “MCH”. Throughout the text of the article, “mean corpuscular hemoglobin concentration” has been corrected to “mean corpuscular hemoglobin” and the abbreviation “MCHC” has been corrected to “MCH”.

In the published article, there was an error in the header, title and legend for Table 1 as published. “MCHC” should be written as “MCH”.

The corrected Table 1 and its legend appear below.

Table 1. The value of Hb and MCH in PW with or without thalassemia genotypes.

In the published article, there was an error in the legend for Table 2, “The levels of Hb and PF in APW with or without ID” as published. “=” should be written as “≥”; “PF: the PF levels in APW” should be written as “PF: the PF levels in all APW”. The corrected Table 2 and its legend appears below.

Table 2. The levels of Hb and PF in APW with or without ID.

In the published article, there was an error. A correction has been made to the section Results, subsection “Analysis of anemia prevalence and hematological phenotype indexes in pregnant women with various thalassemia genotypes”, paragraph 1. This sentence previously stated:

“The anemia rates of αα/–^SEA, –α^3.7/–α^3.7, –α^3.7/–α^4.2, and –α^4.2/–α^4.2 ranged from 35.96 to 37.82% (P < 0.05).”

The corrected sentence appears below:

“The anemia rates of αα/–^SEA, –α^3.7/–α^3.7, –α^3.7/–α^4.2, and –α^4.2/–α^4.2 ranged from 35.96 to 37.82% (P > 0.05).”

A correction has been made to the section Discussion, subsection “Analysis of anemia prevalence and hematological phenotype indexes of pregnant women with various thalassemia genotypes”, paragraph 1. This sentence previously stated:

“The anemia rate among carriers of αα/–^SEA, –α^3.7/–α^3.7, –α^4.2/–α^4.2, and –α^3.7/–α^4.2 ranged from 35.96 to 37.82% (P < 0.05), and no significant differences were observed in Hb levels among those genotypes.”

The corrected sentence appears below:

“The anemia rate among carriers of αα/–^SEA, –α^3.7/–α^3.7, –α^4.2/–α^4.2, and –α^3.7/–α^4.2 ranged from 35.96 to 37.82% (P > 0.05), and no significant differences were observed in Hb levels among those genotypes.”

A correction has been made to the section Discussion, subsection “Prevalence of iron deficiency in anemic pregnant women with various genotypes of thalassemia”, paragraph 1. This sentence previously stated:

“Although there is no large sample, multicenter randomized controlled study that has yet confirmed the need for routine iron supplementation in PW with thalassemia minor genotypes, we suggest that the iron load of APW with β- thalassemia minor genotypes should be monitored dynamically during iron supplementation”

The corrected sentence appears below:

“Although there is no large sample, multicenter randomized controlled study that has yet confirmed the need for routine iron supplementation in PW with thalassemia minor genotypes, we suggest that the ferritin levels of APW with β- thalassemia minor genotypes should be monitored dynamically during iron supplementation”

The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
