Statistical analysis
All statistical analyses were performed using Statistical Package for the Social Sciences (SPSS) version 27 for Windows (SPSS Inc., Chicago, IL, USA). Independent t-test was used to test for statistical significance of differences in the mean values between the old and follow-up data in SCD patients. Paired t-test was used to test for any significant differences between both sides for all vessels between. Pearson’s correlation coefficient was used to test the correlation between TAMMV and the other vascular parameters for each vessel. A p value of <0.05 was considered statistically significant.
