Picture this: You're analyzing clinical trial data where patients can experience multiple types of events—recovery, relapse, or death. Traditional survival analysis falls short because it can't handle these competing risks where one outcome prevents others from occurring. That's where competing risks analysis becomes your statistical superhero.
With Sourcetable's AI-powered platform, you can perform sophisticated competing risks modeling without wrestling with complex statistical software. Our intuitive interface makes it simple to analyze survival data with multiple endpoints, calculate cumulative incidence functions, and interpret results—all while maintaining the flexibility of a spreadsheet.
Competing risks analysis is a statistical method used when subjects can experience one of several mutually exclusive events. Think of it as analyzing a race where multiple finish lines exist, but crossing one prevents you from reaching the others.
Unlike standard survival analysis that focuses on time to a single event, competing risks analysis considers:
This approach provides more nuanced insights than traditional methods, especially in medical research, reliability engineering, and risk assessment where multiple competing outcomes are common.
Let AI guide your competing risks model specification, covariate selection, and assumption testing. Get expert-level statistical modeling without years of training.
Generate compelling cumulative incidence plots, hazard ratio visualizations, and model diagnostics with natural language commands.
Import survival data from clinical databases, research repositories, or Excel files. Our platform handles data preparation and validation automatically.
Share your competing risks models with research teams, stakeholders, and reviewers. Real-time collaboration keeps everyone aligned on methodology and results.
Generate analysis reports that meet regulatory standards for clinical research, with complete audit trails and reproducible methodology.
Perform sophisticated statistical modeling through natural language queries and intuitive spreadsheet operations. Focus on insights, not syntax.
Discover how professionals across industries use competing risks analysis to solve complex problems:
Analyze patient outcomes in oncology trials where patients may experience disease progression, death from other causes, or treatment-related complications. Model competing endpoints to inform treatment decisions.
Study component failure modes in manufacturing systems where parts can fail due to wear, corrosion, or catastrophic events. Optimize maintenance schedules based on competing failure risks.
Model credit defaults where borrowers may default due to unemployment, illness, or economic downturns. Assess portfolio risk with multiple competing scenarios.
Investigate disease outcomes in population health studies where subjects may experience the disease of interest, competing diseases, or death from other causes.
Analyze customer churn patterns where customers may leave due to pricing, service issues, or competitor offerings. Develop targeted retention strategies.
Study species survival with multiple mortality causes like predation, disease, or habitat loss. Inform conservation strategies with competing risk insights.
Follow these steps to perform professional competing risks analysis:
Upload datasets with subject IDs, event times, event types, and covariates. Sourcetable automatically validates data structure and identifies potential issues.
Use natural language to define your competing risks model: 'Analyze time to death or relapse with age, treatment, and stage as covariates.' AI handles the technical specification.
Generate descriptive statistics and preliminary visualizations. Examine event rates, censoring patterns, and covariate distributions across competing risk groups.
Sourcetable fits Fine-Gray subdistribution hazard models, cause-specific hazard models, or both. Compare model performance and assumption validity automatically.
Compute cumulative incidence functions, subdistribution hazard ratios, and confidence intervals. Get intuitive interpretations of all statistical measures.
Create publication-ready plots showing cumulative incidence curves, hazard ratio forest plots, and model diagnostic charts. Customize colors, labels, and themes.
Receive AI-powered interpretation of your competing risks analysis. Understand what hazard ratios mean, identify significant predictors, and assess model fit.
Generate comprehensive reports with methodology, results, and visualizations. Export to PDF, Word, or presentation formats for stakeholder communication.
A pharmaceutical company is analyzing a cancer treatment trial where patients can experience three competing outcomes: disease progression, death from treatment toxicity, or death from other causes. The traditional approach of analyzing each endpoint separately would overestimate the probability of any single event.
Using Sourcetable's competing risks analysis:
A manufacturing company needs to analyze pump failures in their facility. Pumps can fail due to mechanical wear, electrical issues, or external damage. Understanding these competing failure modes helps optimize maintenance strategies.
The analysis reveals:
A subscription service wants to understand why customers cancel. Customers may leave due to pricing concerns, service quality issues, or competitor offerings. Each reason requires different retention strategies.
The competing risks analysis shows:
Sourcetable implements industry-standard competing risks methods with modern computational efficiency:
The subdistribution hazard model directly models the cumulative incidence function for each competing risk. This approach is particularly useful when you want to understand the absolute risk of experiencing a specific event type in the presence of competing risks.
Key features:
Cause-specific models analyze the instantaneous risk of each event type among subjects still at risk. This approach is valuable for understanding the biological or mechanistic processes underlying each competing risk.
Benefits include:
Sourcetable automatically performs comprehensive model validation:
Standard survival analysis focuses on time to a single event, treating other events as censoring. Competing risks analysis explicitly models multiple mutually exclusive events, providing more accurate probability estimates when subjects can experience different types of outcomes.
Use Fine-Gray models when you want to predict absolute risk and understand cumulative incidence in the presence of competing risks. Use cause-specific models when you want to understand the biological mechanisms or instantaneous risk of each event type separately.
Sourcetable automatically handles right censoring, left truncation, and interval censoring. The platform validates censoring patterns and provides diagnostic tools to assess the impact of censoring on your results.
Yes, Sourcetable supports time-varying covariates in both Fine-Gray and cause-specific hazard models. Simply specify your time-dependent variables, and the platform handles the complex data restructuring automatically.
Subdistribution hazard ratios represent the relative risk of experiencing a specific event while accounting for competing risks. A hazard ratio of 1.5 means the risk of that specific event is 50% higher, considering that competing events prevent its occurrence.
Sample size depends on event rates, number of competing risks, and desired statistical power. Sourcetable provides power calculation tools and guidance for sample size planning based on your specific study design and expected effect sizes.
Absolutely. Sourcetable handles any number of competing event types. The platform automatically adjusts model complexity and provides clear visualizations even with many competing risks.
Sourcetable performs comprehensive assumption testing including proportional hazards tests, linearity assessments, and independence checks. The platform provides diagnostic plots and statistical tests with clear interpretations of assumption violations.
