Applied Biostatistics

Our team members have internationally leading expertise in applied biostatistics, covering a broad range of topics such as survival analysis, multi-state modelling or joint modelling.

Methods Development

We are leaders in the development and application of cutting-edge statistical methods, with all of our team members actively involved in methodological research.

Methods Development

Real-World Evidence

At RDA, we understand that real-world evidence is generated by using cutting edge methods from biostatistics and epidemiology on observational data to obtain meaning and impactful insights.

Clinical Trial Services

We do provide clinical trial services for clinical development and late phase clinical trials.

Clinical Trial Services

Our offerings

Solution 1

Functional service provider (FSP). You get exclusive access to one (or more) of our team members’ time at a percentage that suits you best.

We recommend this solution for projects estimated to go on for a longer period, or for academic groups looking for “their own” statistician.

Solution 2

Tasked-based. You pay a fixed fee from initiation of a project to complete delivery.

We recommend this solution for larger projects consisting of one or more clearly defined tasks to be performed during a well-defined time window.

Solution 3

Hourly. All work is tracked with a fixed fee per hour.

We recommend this solution for small to medium sized projects, where the scope and estimated total time to complete the work is difficult to judge beforehand.

Introduction to Epidemiological Study Designs

This video offers a comprehensive introduction to epidemiological study designs, emphasising their classification, key definitions, strengths, limitations, and practical applications. We will dive into the most commonly used study designs, exploring their structure, purpose, and the contexts in which they are most effective. Throughout the video, real-world case studies of landmark research will be used […]

Real-World Evidence (RWE)

Real-World Evidence Real-world evidence (RWE) refers to data and information that, unlike data generated in clinical trials conducted in controlled environments, has been obtained from everyday clinical practice, patient registers, or other sources outside the clinical trial setting. RWE plays a crucial role in complementing traditional clinical trial data, providing insights into the safety, effectiveness, […]

State-of-the-art statistical models for modern HTA

At @RedDoorAnalytics, we develop methodology and software for efficient modelling of biomarkers, measured repeatedly over time, jointly with survival outcomes, which are being increasingly used in cancer settings. We have also developed methods and software for general non-Markov multi-state survival analysis, allowing for the development of more plausible natural history models, where patient history can […]

Multilevel (hierarchical) survival models: Estimation, prediction, interpretation

Hierarchical time-to-event data is common across various research domains. In the medical field, for instance, patients are often nested within hospitals and regions, while in education, students are nested within schools. In these settings, the outcome is typically measured at the individual level, with covariates recorded at any level of the hierarchy. This hierarchical structure […]

What are competing risks?

Competing risks In survival analysis, competing risks refer to the situation when an individual is at risk of experiencing an event that precludes the event under study to occur. Competing risks commonly occur in studies of cause-specific mortality, as all other causes of death than the one under study might happen before the individuals “have […]

What is immortal time bias?

Immortal time bias Immortal time bias is a type of bias that can occur in observational research when the study design allows for a period of time during which the outcome of interest cannot occur, often referred to as “immortal time”. Simply put, immortal time bias occurs when information from a future event is incorporated into the […]

What is the proportional hazards assumption?

Proportional hazards Proportional hazards in survival analysis means that the rate at which an event of interest occurs over time for two or more groups or individuals is proportional over time. Specifically, it assumes that the hazard ratio, which represents the relative rate of an event occurring between two groups or individuals, is constant over […]

What is censoring?

Censoring refers to a situation in survival analysis where the event of interest is not observed for some of the individuals under study. In this Statistical Primer, we’ll define three types of censoring often seen in survival analysis studies. Censoring occurs when the information on the survival time is incomplete or only partially observed. Censoring […]
