※Indicates the t-test result was significant (p < 0.05).
The bold values indicate the t-test result was significant (p < 0.05).
The duration of microstate C of 17 patients had significant increased after 20 min of hyperbaric oxygen therapy compared with pre-treatment (p < 0.05). And the contribution of microstate D had significant reduced (p < 0.05). Other microstate parameters did not change significantly.
