    Snippet: Thereafter, patients were divided into the ON and non-ON groups based on MRI findings. Results were reported as mean±standard deviation (SD) for the quantitative variables and percentages for the categorical variables. The groups were compared using the Student's t-test for the continuous variables and the Chi-square test for the categorical variables. P values of 0.05 or less were considered statistically significant. All the statistical analys.....
