^aP = 0.01.

¹n = 442 due to four patients for whom the localization was not documented.

For sex, age, and disease duration, comparisons were made between two groups using independent sample t-tests; for localization, the comparison was made across three groups using the Kruskal-Wallis H test. IQR: Interquartile range.
