Biostatistics, the application of statistics to biological and medical data, is often misunderstood. This review clarifies basic statistical principles and common errors in orthopaedic research publications.

Area of Science:

  • Biostatistics
  • Medical Statistics
  • Orthopaedic Research

Background:

  • Statistical principles are increasingly important in data analysis.
  • Biostatistics is often poorly understood and mishandled in medical research.
  • Orthopaedic research frequently encounters statistical errors.

Purpose of the Study:

  • To introduce basic data analysis principles in orthopaedic research.
  • To outline prominent areas in medical statistics.
  • To identify common statistical errors in orthopaedic publications.

Main Methods:

  • Literature review of biostatistics and medical statistics.
  • Analysis of common errors in published orthopaedic research.
  • Focus on principles relevant to the Journal of Bone and Joint Surgery.

Main Results:

  • Biostatistics and its principles are not universally understood.
  • Several common statistical errors are prevalent in orthopaedic journals.
  • Understanding these errors is crucial for manuscript review.

Conclusions:

  • Improved understanding and application of biostatistics are needed in orthopaedic research.
  • Awareness of common statistical pitfalls can enhance research quality.
  • This review aims to guide researchers and reviewers in orthopaedic statistics.
