In the univariate Cox regression analysis ( Table 2 ), a borderline significant association was observed between low UAR (<1) and improved PFS (HR = 0.50, 95% CI: 0.24–1.05, p = 0.06).
In the univariate Cox regression analysis ( Table 2 ), a borderline significant association was observed between low UAR (<1) and improved PFS (HR = 0.50, 95% CI: 0.24–1.05, p = 0.06).
Although the association between UAR and PFS demonstrated borderline significance in the Kaplan–Meier analyses, it is noteworthy that it became statistically significant in the multivariate analyses.
Among the other variables, only menopausal status showed a trend toward statistical significance, although this did not reach significance (HR = 1.46 for premenopausal status, p = 0.23).
In the multivariate analysis, variables considered clinically important or approaching significance in univariate analysis, including age, comorbidity, menopausal status and UAR, were subsequently incorporated into the model.
