Latest Updates

TreeAge Pro 2025, Release 2

• Combine Survival/Hazard Estimates *

  • Combine multiple estimates of survival or hazard into a single curve.

  • Transition from one estimate to another to form a single survival or hazard curve.

  • Blend multiple estimates over the same time period to represent low and high bounds for sensitivity analysis.

  • Combine multiple transitions and blends into a complex curve.

• TreeAge Pro Web Enhancements

  • Share Partitioned Survival Models including Survival Curves, Hazard Curves, Cost-Effectiveness and more.

  • Share Probabilistic Sensitivity Analysis including Acceptability Curves, ICE Scatterplots and more.

  • Users can save graph images and Excel reports for all model outputs.

• Improved Graphs to Visualize Distributions

  • When adding/editing distributions, PDF/CDF graphs visually represent the set of possible samples.

  • These graphs were enhanced with options to show 95% or 99% of samples to provide better visibility.

• Plot Proportional Hazards from Kaplan-Meier Tables

  • Graph two or more Kaplan-Meier Survival Tables and distributions on a logarithmic graph to see if the hazards are proportional.

  • Proportional hazards indicate a fixed hazard ratio between any two survival estimates.

* Features require your license have active Maintenance.

TreeAge Pro 2025, R1 includes the following updates.

• Markov Model Wizard: With the Markov Model Wizard, you can create your model in a few simple steps. It’s never been easier to build a Markov Model with TreeAge Pro.

• Markov Plot : The Markov Plot View allows you to graph Markov disease progression with a single click. You can then overlay the Markov Plot with survival tables to see how closely your model matches with source clinical data.

• Survival to Hazard Conversion Enhancements: New conversion options better match survival by applying hazards earlier. This includes better support for spline tables.

• New Table Controls and Functions: Support spline interpolation. New function for reverse table lookups.

• Allow Negative Distribution Parameters: Gompertz and Generalized Gamma distribution types.

• Combine Survival Curve Graphs: From Partitioned Survival models and Markov model PartSA output graph.

• Add Point to Graph: Add a specific point to any graph to highlight values.

TreeAge Pro 2024, R1 & R2 include the following updates.

• Web Model Sharing: Share your model on the web. You define the web functionality by choosing which inputs can be edited and which analyses can be run. Then share the model with colleagues, so they can review and analyze the model.

• Add Distribution Wizard for PSA: Select a model input to include in Probabilistic Sensitivity Analysis. With just a few mouse clicks, the wizard creates the appropriate distribution and references it in the model.

• Visualize Survival Estimates with the Survival Plot: Compare different estimates of survival with the Survival Plot View. Compare survival and/or hazard functions from distributions, tables and formulas to determine which is most accurate and appropriate for your model. No model structure is required, just add survival/hazard series and review the graphs. Export your survival estimate comparison to image or PDF files to share with colleagues.
