Notes: The data are presented as mean ± SD. A one-way analysis of variance was used to calculate the P-values using the Epi Info™ software Version 6 (Atlanta, GA, USA).
Abbreviations: BMI, body mass index; HAPE, high altitude pulmonary edema; HAPE-c, HAPE controls; HAPE-p, HAPE patients; HLs, highlanders; MAP, mean arterial pressure; SaO2, arterial oxygen saturation; SD, standard deviation.
