2.4. Statistical analyzes
We applied the Wilcoxon signed rank test to assess changes in
the objective and subjective cognitive impairment and clinical
measures from baseline to endpoint. The chances of obtaining
false-positive results (type I errors) when multiple pair wise tests
are performed on a single set of data were reduced by the Bonferroni
correction (po0.0038) by dividing the p-Value by the
number of comparisons being made.
