Hazard Ratio Blocks: Age × Tumor Size × HR (3D Visualization)
This interactive 3D visualization displays hazard ratios (HR) comparing surgery vs. non-surgery across three clinical dimensions: age category, tumor size, and HR height.
Height of each block represents the hazard ratio (HR).
Color gradient (blue → cyan → orange → red) encodes HR magnitude, with warmer colors indicating higher risk.
Axes:
X-axis: Age categories (<65, 65–75, >75)
Y-axis: Tumor size (Small, Medium, Large)
Z-axis: Hazard ratio (HR)
Data modeled using Cox proportional hazards on SEER cohort; only strata with sufficient sample size and model convergence are shown.
This visualization helps clinicians and researchers quickly identify risk patterns across patient subgroups, supporting evidence-based decision-making.
Analysis of Political Tolerance Among Faculty Ranks: An Analysis of Covariance Approach
This ANCOVA study reveals faculty rank significantly modifies how political tolerance changes with age, showing full professors become less tolerant with age while junior faculty remain stable.
