Study design sets important limits on what conclusions the data can reasonably support. A suitably qualified biostatistics expert can examine the research question, comparison groups, randomization or matching, outcome definitions, sample-size calculations, inclusion and exclusion criteria, planned statistical methods, and sources of bias or variability. The analysis can also address whether the statistical approach corresponds to the type of study and the data actually collected.
Results can be influenced by missing data, small sample sizes, multiple comparisons, confounding variables, model assumptions, outcome selection, loss to follow-up, or inappropriate statistical tests. A suitably qualified biostatistics expert witness can assess how those factors were handled and whether they materially affect the interpretation of the reported findings. The importance of any particular issue depends on the study design and analytical method involved.
For regression analysis, the expert may examine variable selection, model specification, adjustment for potential confounders, underlying assumptions, effect estimates, confidence intervals, and model diagnostics. Survival analysis can require additional consideration of time-to-event definitions, censoring, follow-up periods, risk sets, and the statistical model used. The goal is to determine whether the analysis was appropriately constructed and whether its reported interpretation is supported by the data.
Biostatistics applies statistical methods specifically to biological, medical, and health-related research and data. Epidemiology more directly examines patterns, determinants, and distributions of health-related events in populations, while Statistics encompasses statistical theory and applications across many fields. The disciplines can overlap, so the appropriate expert should match the study, dataset, methodology, and scientific question actually disputed.
