The t tests were performed to compare the baseline performance to the 6-month performance in all patients, PCSI population and non-PSCI population, respectively.
#t tests were also performed between PCSI population and non-PSC population at 6months.
*P value referred to comparison between PSCI and non-PSCI patients at 6 months.
Variables were expressed as mean ± standard deviation (SD).
