Figure 2. Linear Regression of Residual Platinum Value and Continuous Variables.

Simple linear regression results are presented for A) age at diagnosis, B) creatinine clearance, and C) LH levels. R² and p-values for linear regression are reported for all phenotypes. A Spearman rank correlation test (r_sp) was also performed on LH levels due to its positive skew distribution, and results are shown in panel C. Fitted linear regression lines are highlighted in gray and 95% confidence intervals are indicated by the light gray shaded regions.
