2. Figure 1
Altitude profile is shown in black triangles over the 19 days of the trek. The days of wobble board tests are indicated by arrows. The proportion of subjects with self-reported symptomatic unsteadiness is shown in the vertical columns, with the morning questionnaire as white bars and the evening questionnaire as stippled bars.

4. Figure 3
Wobble board (number of contacts) results at different altitudes. At each altitude, the p values refer to the difference between the younger (31 years of age or less, closed circles) compared with older (over 31 years of age, open circles) subjects. The crosses refer to subjects with AMS at 4650m and 5005m.
