Hematological adaptations following descent from high altitude to low altitude.

Data are presented as mean ± SD with the number of subjects (M,W) indicated in parentheses. Subjects were studied at sea level, at 5260 m after 16 days high altitude acclimatization, and upon initial return to 5260 m after descent to 1525 m for 7 (POST7) or 21 (POST21) days. Linear mixed model statistical analyses were performed to examine the effects of time (with POST as the reference), group (POST7 versus POST21) and a time × group interaction. Effects were accepted as significant when p≤0.05. There were no significant effects of group or any significant group × time interactions (all p>0.05).Hematological adaptations following descent from high altitude to low altitude.数据以均数±标准差（Standard Deviation，SD）呈现，受试者例数（男性(M)、女性(W)）以括号标注。受试者分别在以下三个场景接受研究：海平面环境、经16天高原习服后的5260米海拔处，以及从1525米海拔下降停留7天（记为POST7）或21天（记为POST21）后初次返回5260米海拔时。采用线性混合模型（Linear Mixed Model）开展统计分析，以考察时间效应（以POST为参照）、组别效应（POST7组与POST21组）以及时间×组别交互效应。当p≤0.05时，认定效应具有统计学显著性。未观察到组别主效应或任何显著的时间×组别交互效应（所有p>0.05）。从高海拔下降至低海拔后的血液学适应性变化。
