Diagram of the ascent profile and sample days. SL1 and SL2 occurred 1 to 2 months before and after altitude, respectively; SL1=pre-expedition sea level sample day, Edinburgh (no drugs taken); CH1=day 1 at Chacaltaya Laboratory (5200m); CH3=day 3 at Chacaltaya; CH7=day 7 at Chacaltaya; SL2=postexpedition sea level sample day, Edinburgh.

3. Figure 2
The change in systolic blood pressure on standing comparing those volunteers who felt faint on standing with those who did not. SL1=pre-expedition sea level sample day (no drugs taken); CH1=day 1 at Chacaltaya Laboratory (5200m); CH3=day 3 at Chacaltaya; CH7=day 7 at Chacaltaya; SL2=postexpedition sea level sample day, Edinburgh; P values shown above line, unpaired t test symptoms vs no symptoms, with Bonferroni's correction; Error bars represent the standard error.
