Statistical analysis
All statistical analyses were performed using the R version 4.0.3.
Continuous variables are presented as mean ± standard deviation.
Categorical variables are presented as numbers and percentages. The
Student’s t -test was used to compare continuous variables, while
the Fisher’s exact test was used to compare the categorical variables.
The data analytic strategy for the association between the number of
repetitions of focal activations and CL or CLSD included using
mixed-effects models, since they can account for individual variability.
Statistical significance was set at p < 0.05.
