Univariate Cox Regression Analysis In the univariate Cox regression analysis (the summary is presented in Table 3 ), the older age at onset had a higher hazard of mortality, but the result was borderline significant (HR: 1.03; 95% CI 0.99–1.07, p = 0.06).
A slight trend was noted in diagnostic delay (14.5 vs. 9 months, p = 0.26) and treatment (18.5 vs. 9.5 months, p = 0.14) in female patients compared to male but without reaching statistical significance.
In our cohort, older age at onset was associated with an increased risk of mortality, although this association did not reach statistical significance, likely due to the relatively small sample size.
