Biostatistics

Statistical design and analysis that is pre-specified, reproducible and clearly explained.

Overview

Good statistics begins with a clear question. We help teams translate objectives and estimands into a pre-specified analysis plan, and then execute that plan transparently.

We write for two audiences at once: the regulator who needs rigor, and the clinician who needs to understand what the numbers mean.

Standards & frameworks we work within

  • ICH E9 and E9(R1) estimands framework
  • ICH E3 report structure
  • CONSORT reporting principles
  • Applicable FDA / EMA statistical guidance

These are frameworks we work within or align to. They do not imply certification, accreditation or endorsement.

What we deliver

  • Sample size and power considerations
  • Statistical analysis plan authoring and review
  • Randomisation specification support
  • Interim, primary and exploratory analyses
  • Survival, longitudinal and categorical data methods
  • Statistical sections of protocols and reports
