Following publication of the original article [1], the authors have inadvertently made a few minor mistakes in the figure and tables.

First, Fig. 5 is incorrect, as the absolute instead of the relative volumes are depicted. The legend refers to the figure below, indeed showing no relationship between the absolute increase of PF and the relative (%) increase of CAT and EAT.

Correct version of Fig. 5

Showing no relationship of increasing volume of PF to the relative contribution (%) of the CAT and EAT component (a) and (b), hence the contribution of both compartments remains equal despite different volumes of total PF. EAT and CAT volume show a wide variation, they are linearly associated to each other (c), indicating that both increase with an increase of PF.

The figure in the paper shows the absolute volumes, which therefore are linearly correlated with the total PF volume. The capitation and text below the figure however, refer to the new figure above.

Old figure:

The second mistake involves the p-values of Tables 3 and 4. Although the data and the 95% CI intervals are correct, and hence significance could have been concluded from the data, unfortunately the reported p-values were incorrect. Below we have corrected the tables and added the correct P-values to the tables. After correction of the p-values, only the Left atrial volume index (LAVI) is associated with the PF after correction for age, BMI and gender and the correlation of PF with the other parameters of diastolic function is lost. As a result, part of the results may be biased by age, gender and BMI. Nonetheless, the mechanical effect on the left atrium remains and the changed results do not alter the discussion and/or the message of the paper.

These two errors had no effect on the scientific content or conclusions of the paper. We deeply apologize that this occurred, and take responsibility for the error and hereby present the correction.
