In the original article, there was a mistake in Table 1 as published. The value displayed for heart rate on day 0 for the PWB40 group was incorrect. The incorrect value was 349 ± 59, it has been replaced by the correct value 397 ± 28. The corrected Table 1 appears below.

Weekly measurement of plasma parameters, foot oxygenation, and heart rate; and wet mass of the adrenal glands and spleen after 14 days of PWB.
n = 7 per group. Results are presented as mean ± SEM and were analyzed using 2-way repeated measures ANOVAs followed by Sidak's test (longitudinal measures) or unpaired Student's t-test (terminal measures). Significant results were not detected.
