Association between Body Water Status and Acute Mountain Sickness
Figure 2
Changes in the vector length and the 95% confidence ellipses of the AMS+ and AMS− group from before to after the hypoxia exposure.
In both groups a significant shortening of the vector was present (p<0.001, paired one sample Hotelling's T2 test) indicating fluid gain [22]. There were no differences between groups (two sample Hotelling's T2 test).
