Following publication of the original article it was reported that there were errors in Tables 2 and 6 and Supplementary Table 3.
Regarding Table 2 and Supplementary Table 3, for the variable long squeeze PV (3/3) 10^4^mmHg².cm of female one value was mistakenly included in the original in the scale of 10^3^ instead of 10^4^, which misled the analysis of the maximum value and the mean, although the median and interquartile range were not affected. The original standard deviation reported was 18.5, while the correct value is 5.6. Additionally, the mean value, originally reported as 11.8, is 8.3.
The corrected Table 2 and Supplementary Table 3 are given in this Correction with the corrected values highlighted in italics in Table 2.
