Corrigendum: The Survey of Birth Defects Rate Based on Birth Registration System

In the article titled, “The Survey of Birth Defects Rate on Birth Registration System” published in pages 7-14, issue 1, vol. 128 of Chinese Medical Journal,[1] the following sentences have “‰” sign written incorrectly as “%” sign:

The sentence “The birth defect rate declined from 9.18% in 2003 to 7.00% in 2012 (χ² = 45.001, P < 0.01) with a mean value of 7.85%.” should be written as “The birth defect rate declined from 9.18‰ in 2003 to 7.00‰ in 2012 (χ² = 45.001, P < 0.01) with a mean value of 7.85‰”.

The sentence “The average birth defects rate of 8.11% in rural area was higher than that in urban area (7.56%) and much higher in males (8.28%) than that in females (7.18%).” should be written as “The average birth defects rate of 8.11‰ in rural area was higher than that in urban area (7.56‰) and much higher in males (8.28‰) than that in females (7.18‰).”

The sentence “5,551 (84.86%) newborns with single deformity, the incidence was 6.67%; 990 (15.14%) of them born with multiple deformities, the rate was 1.19%” should be written as “5,551 (84.86%) newborns with single deformity, the incidence was 6.67‰; 990 (15.14%) of them born with multiple deformities, the rate was 1.19‰”.

The sentence “The differences between males and females were significant in 2005 (males: 8.4%; females: 6.7%), 2006 (males: 8.72%; females: 6.82%), 2007 (males: 7.98%; females: 6.54%), and 20l0 (males: 9.3%; females: 7.48%)” should be written as “The differences between males and females were significant in 2005 (males: 8.4‰; females: 6.7‰), 2006 (males: 8.72‰; females: 6.82‰), 2007 (males: 7.98‰; females: 6.54‰), and 20l0 (males: 9.3‰; females: 7.48‰)”.

The sentence “Total of 3,650 perinatal deaths was registered during 2003-2012 with a mortality of 4.38%, which significantly declined from 8.63% in 2003 to 4.15% in 2012” should be written as “Total of 3,650 perinatal deaths was registered during 2003-2012 with a mortality of 4.38‰, which significantly declined from 8.63‰ in 2003 to 4.15‰ in 2012”.

The sentences “The average incidence of NTDs was 1.36%. Fortunately, it decreased from 2.63% in 2003 to 0.90% with a total of 59.48% declined. In nationwide, the incidence of perinatal NTDs decreased from 2.74% in 1987 to 0.45% in 2011” should be written as “The average incidence of NTDs was 1.36‰. Fortunately, it decreased from 2.63‰ in 2003 to 0.90‰ with a total of 59.48% declined. In nationwide, the incidence of perinatal NTDs decreased from 2.74‰ in 1987 to 0.45‰ in 2011”.

The sentence “With a mean value of 0.69%, the incidence of CHD rose from 0.38% in 2003 to 1.17% in 2012” should be written as “With a mean value of 0.69‰, the incidence of CHD rose from 0.38‰ in 2003 to 1.17‰ in 2012”.

The sentences “In 2009-2011, the national incidences of PKU were 0.073%, 0.076% and 0.072%, respectively. Meanwhile, it was 0.701%, 0.43%and 0.819% in Xi’an which marked higher than the former. During the same period, the national incidences of hypothyroidism were 0.49%, 0.463%, 0.475%, which were 0.448%, 0.329% and 0.48% in Xi’an” should be written as “In 2009-2011, the national incidences of PKU were 0.073‰, 0.076‰ and 0.072‰, respectively. Meanwhile, it was 0.701‰, 0.43‰ and 0.819‰ in Xi’an which marked higher than the former. During the same period, the national incidences of hypothyroidism were 0.49‰, 0.463‰, 0.475‰, which were 0.448‰, 0.329‰ and 0.48‰ in Xi’an”.

In Table 1, the “%” sign for columns “Birth defect rate”, “Single deformity incidence” and “Multiple deformities incidence” is incorrect and should written as “‰”. In Table 2, the “%” sign for columns “Urban Incidence”, “Rural Incidence”, “CHD with LBW Incidence” and “CHD with normal birth weight” is incorrect and should written as “‰”. In Table 3, the “%” sign for columns “Urban Incidence” and “Rural Incidence” is incorrect and should written as “‰”.
