Analyzing real-world, observational data requires specialized statistical skills. Our biostatisticians work closely with RTI-HS outcomes researchers to design and analyze data from a wide range of study types, including surveys, cross-sectional or longitudinal non-interventional studies, registries, chart abstractions, and electronic medical records (EMRs).
Registry and Database Analyses
Our biostatisticians are knowledgeable in the statistical techniques necessary to analyze non-randomized studies. These studies require special consideration to address potential confounding, typically using methods such as propensity scores., Our researchers have the necessary expertise to define exposure and outcome(s), and to account for censoring and missing data. In addition, we assist researchers in the interpretation of the results and examination of potential biases so that you can be confident in using your results to make informed decisions.
Whether it is a simple survey or a complex multi-stage survey design, our statisticians have extensive experience in the planning and analysis of surveys including survey sampling and weighting. We understand that analyses of complex sample surveys require the use of appropriate statistical software that accounts for the sample design so that the results accurately answer your research questions about the population of interest.
