Correction

Following publication of our article [1], we noted that Table 2 (1) was published with several incorrect data values. The correct values should be:

aY, yes; N, no; petCO2, partial pressure of end-tidal carbon dioxide; NT-proBNP, amino terminal pro-brain natriuretic peptide; ECG, electrocardiogram; HF, heart failure; CHF, congestive heart failure; AMI, acute myocardial infarction; SaO2, arterial oxygen saturation; ETI, endotracheal intubation; COPD, chronic obstructive pulmonary disease. bResults are presented as means ± standard deviation for normally distributed data or ratio or percentage for other variables. cUnivariate comparison was made using the χ2 test for categorical variables and a t-test for continuous variables. For evaluation of diagnostic accuracy, patients were divided into two groups: HF-related acute dyspnea and pulmonary-related acute dyspnea (COPD/asthma). dModified Boston criteria according to Table 1 and Remes et al. [6].

Under the "Pulmonary-related dyspnea" column:

- Sex, males/females (%) should read 65.2/34.8

- Cough, Y/N should read 48/41

- Wheezes, Y/N should read 68/21

- ECG-normal sinus rhythm, Y/N should read 72/17

- Asthma/COPD medications (Y/N) should read 78/11

- Previous asthma/COPD (Y/N) should read 70/19

Under the "Acute HF-related dyspnea" column:

- Sex, males/females (%) should read 57.9/42.1

- Nocturnal dyspnea (Y/N) should read 43/86

- Orthopnea (Y/N) should read 39/90

- Rales (Y/N) should read 76/53

- Jugular venous distension (Y/N) should read 30/99

- HF medications (Y/N) should read 83/46

- Previous AMI (Y/N) should read 45/84

- Previous CHF (Y/N) should read 80/49

- Previous asthma/COPD (Y/N) should read 27/102
