A four-component clinical survival analysis figure in a publication-style layout. Make the large left panel a Kaplan-Meier overall survival plot with two stepped curves comparing biomarker-high (red) versus biomarker-low (blue) groups, x-axis "Time since diagnosis (months)" from 0 to 60, y-axis "Overall survival probability" from 0 to 1.0, with shaded 95% confidence bands and small censoring tick marks. Beneath it place a number-at-risk table listing both groups at 0, 12, 24, 36, 48, 60 months (e.g. High: 210, 142, 88, 51, 22, 9; Low: 198, 176, 151, 120, 94, 60). Annotate the log-rank p-value (p < 0.001) and hazard ratio HR = 1.82 (95% CI 1.41-2.35). On the right, add a subgroup forest plot with square markers and horizontal CI lines for Age >=65, Sex, Stage III/IV, ECOG 0-1, and Mutation status, with a vertical line at HR = 1. Clean publication quality, tidy alignment, legible labels, white background.
