Background We evaluated the efficacy of acetazolamide in preventing adverse altitude effects
in patients with moderate to severe chronic obstructive pulmonary disease (COPD) and in …

… p < 0.05 vs. rest at the corresponding altitude; ¶ p < 0.05 vs. isotime at 490 m. VʹO2, oxygen
uptake; VʹCO2, carbon dioxide output; SpO2, arterial oxygen saturation by pulse oximetry; …

… As expected, P aO 2 and S aO 2 were significantly lower in highlanders compared to
lowlanders. Highlanders had higher haemoglobin concentration, haematocrit, heart rate, diastolic …

… Age, sex, and all predictor variables for which univariate analysis revealed an association
with P<0.2 were entered into a subsequent multivariable model. A probability of P<0.05 was …

changes between both drugs, however, was only seen in the antero-posterior plane, …

… In multivariable analysis, larger body mass index (p = 0.046), an increase in SpO 2 (p <

… Constant work-rate cycle endurance time was significantly reduced at altitude when patients
received placebo, p = 0.046 (Table 2). All patients performed an incremental exercise test at …
