Summary of results for Mindstreams cognitive indices scores.

Abbreviations:
Values are presented as mean ± STD. P1 stands for the p values for baseline comparison of treated and crossover group; P2 stands for the p values for comparison of the second measurement to baseline in the same group; P3 stands for the p values for comparison of pre- and post-HBOT in the crossover group; P4 stands for the p values for endpoint scores comparison following treatment in both groups. The baseline mean cognitive scores of all four indices were close in the two groups, with no significant difference. The HBOT treatments of both groups led to statistically significant improvements in the mean scores of all four indices as oppose to no significant improvement after control period alone. The tables are discussed in details in the results section.
