Extravascular lung water index measurement in critically ill children does not correlate with a chest x-ray score of pulmonary edema

After publication of our article [1], we noticed errors in Tables 2 and 3. Under the 'Weight' column in Table 2, decimal points should have been included in this data.

Table 2.

Table 3.

Values of several measurements

Variable	Value
MAP (mmHg)	65 (57 to 76)
Heart rate (bpm)	139 (118 to 153)
Cardiac index (l/min/m2)	4.00 (3.17 to 5.19)
GEDVI (ml/m2)	432 (369 to 528)
EVLWI (ml/kg)	16 (13 to 21)
Chest x-ray score	133 (90 to 204)
A-a gradient (mmHg)	119 (74 to 168)
PaO2/FiO2 (mmHg)	283 (226 to 374)
PEEP (cmH2O)	6 (5 to 8)

Median (interquartile range).

For Table 3, the interquartile value for EVLWI should read 13 to 21 instead of 13 to 121.

The descriptions of the tables in the article are unchanged, and the corrected tables are provided here (Table 2 overleaf).
