  1. Data represent means (SD) or frequencies (%); there are no significant differences between the groups, p < 0.05-Exact Fisher Yates Test; MMSE: Mini-Mental State Examination. aMinimum arterial oxygen saturation measured in the Hypoxic Test
  2. For the measured values of each of the listed variables, the two difference lists (end value - initial value for normoxia, hypoxia) were tested for normal distribution using the Kolmogoroff-Smirnov test
  3. p-values between the groups. If both lists were significantly normally distributed (p < 0.95), the p-value was determined by the t-test, otherwise by the (nonparametric) U-test marked with c; comparison of rates is tested with Exact Fisher Test marked withb
