What the literature leaves open

  • Limited understanding of the relative effectiveness of live high-train high and modified live high-train low strategies. Difficulty in comparing the effects of the two strategies due to differences in study designs and outcome measures.

  • The study identifies a need to analyze the risk of hypoxia among short-term residents in the Qinghai-Xizang Plateau. There is a lack of understanding of the key drivers of near-surface oxygen distribution and the spatial distribution of hypoxia hazard.
