ARTICLE: Alvares BR, Della Torre OH, Mezzacappa MA. Sensitivity of upper gastrointestinal series in the diagnosis of gastroesophageal reflux in premature. Radiol Bras. 2011 Jul/Ago;44(4):211–214. In the “Abstract” (p. 211), line 7: The UGI series sensitivity was of 56.1% (CI 95%: 39.9–71.2%), should be: The UGI series sensitivity was of 39.0 (CI 95%: 25.7–54.3%). In the “Resumo” (p. 211), line 7: A sensibilidade da seriografia foi de 56,1% (IC 95%: 39,9–71,2%), should be: A sensibilidade da seriografia foi de 39,0% (IC 95%: 25,7–54,3%). On Table 2 (p. 213), first line: 23, should be: 16. In the footnote to the Table: Sensitivity = 56.1%; CI 95%: 39.9–71.2%, should be: Sensitivity = 39.0%; CI 95%: 25.7–54.3%. In the “Discussion” (p. 213), third paragraph, line 12: In the present study, we found sensitivity of 56.1% (CI 95% of 39.9–71.2%), higher than that described in the literature. However, considering that the present study evaluated exclusively preterm neonates, the authors could not establish an accurate sensitivity comparison, should be: In the present study, sensitivity of 39.0% (CI 95% of 25.7–54.3%) was found, similar to that reported in the literature. However, considering that the present study evaluated exclusively preterm neonates, the authors could not establish an accurate sensitivity comparison.
