SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enables researchers to design and emulate target trials using real-world data (RWD) to generate credible real-world evidence (RWE), addressing gaps in traditional randomized evidence with observational data.

Core Features & Use Cases

  • Target trial emulation: specify eligibility, treatment strategies, follow-up, and outcomes to emulate a randomized trial using observational data.
  • Propensity score methods: estimate and apply weights or matching to balance covariates between groups.
  • External control arms: integrate external data sources to augment trial comparisons and enhance generalizability.
  • Time-varying confounding: implement sequential trial emulation and marginal structural models to address dynamic treatment regimens.
  • Survival and causal analyses: leverage survival models and causal inference techniques to estimate effects over time.
  • Data quality and reporting: best practices for data quality checks and transparent reporting of RWE methods.

Quick Start

Load real-world data, configure a target trial emulation workflow, and run the TrialEmulation analyses to generate emulated trial results.

FAQPage Schema
How do I emulate a target trial using real-world data in R?

To emulate a target trial using real-world data in R, configure a workflow specifying eligibility, treatment strategies, follow-up, and outcomes. Run the TrialEmulation package to quantify comparative effectiveness through observational data.

What is target trial emulation for causal inference?

Target trial emulation is a causal inference framework that designs observational studies to mimic randomized trials. It specifies eligibility, treatment strategies, and follow-up to generate credible real-world evidence without actual randomization.

How do I handle time-varying confounding in observational studies?

Handle time-varying confounding in observational studies by implementing sequential trial emulation and marginal structural models. These methods address dynamic treatment regimens to estimate accurate causal effects over time.

Can I use propensity score methods for external control arms in R?

Yes, you can apply propensity score methods for external control arms in R. Estimate and apply weights or matching to balance covariates between groups, integrating external data sources to augment trial comparisons.

What is the best way to quantify comparative effectiveness with real-world evidence?

The best way to quantify comparative effectiveness with real-world evidence is by leveraging survival models and propensity score methods. This combination estimates treatment effects over time while balancing baseline covariates.

Does target trial emulation support survival analysis workflows?

Yes, target trial emulation supports survival analysis workflows. Leverage survival models and causal inference techniques to estimate comparative effectiveness over time, addressing dynamic treatment regimens through sequential trial emulation.
