Correction to: Early Childhood Developmental Status in Low- and Middle-Income Countries: National,Regional,and Global Prevalence Estimates Using Predictive Modeling (PLOS Medicine,(2016),13,6,(e1002034),10.1371/journal.pmed.1002034)

The following corrections referenced within the text correspond to the pdf version of this article. on page 2,paragraph 2 within the abstract under the heading methods and findings the authors have revised the following sentence: applying this model to all lmics,we estimate that 81.0 million children ages 3 and 4 y (95% ci 49.2 million,113.3 million) in lmics experienced low cognitive and/or socioemotional development in 2010,with the largest number of affected children in sub-saharan africa (29.5 million; 44.0% of children ages 3 and 4 y),followed by south asia (27.8 million; 37.8%) and the east asia and pacific region (15.2 million; 26.0%). beginning on page 13,paragraph 5 of the results,the authors have revised the following sentences: in table 4,we show our global estimates of the number and percentage of children with low cognitive and/or socioemotional development,which suggests that 81.0 million 3- and 4-y-old children (95% ci 49.2 million,113.3 million) experienced low cognitive and/or socioemotional development in 2010 as measured by the ecdi. this corresponds to a global prevalence in lmics of 33.0% (95% ci 20.0%,46.2%). the highest prevalences of low cognitive and/or socioemotional development were estimated for sub-saharan africa (44.0%; 95% ci 30.8%,57.1%) and south asia (37.8%; 95% ci 24.7%,51.0%),whereas the lowest prevalences were estimated for the latin america/caribbean region (18.7%; 95% ci 6.1%,31.9%) and the north africa/middle east/central asia region (18.5%,95% ci 6.5%,31.6%). sub-saharan africa and south asia also account for the majority of predicted children with low development,with an estimated 29.5 (95% ci 20.7,38.3) and 27.8 (95% ci 18.1,37.4) million 3- and 4-y-olds,respectively. on page 14,paragraph 6 of the results,the authors have revised the following sentences: the country with the highest estimated number of children with low development was india (17.2 million children),followed by china (6.7 million) and nigeria (6.0 million). the estimated percentage of children with low cognitive and/or socioemotional development ranged from as few as 4.8% of children in qatar to 67% of children in chad. on page 15,paragraph 2 of the discussion,the authors have revised 49.6% to 49.7%. errors within the reporting of these datasets have affected tables 3 and 4 respectively. the authors have provided the corrected tables below. (table presented.) (table presented.) fig 7 is incorrect. the authors have provided a corrected version here. (figure presented.) s3 and s4 tables contained incorrect datasets. the authors have provided the corrected tables below. supporting information s3 table mics/dhs versus non-mics/dhs low- and middle-income country characteristics. this file includes corrected datasets for s3 table.
