[Statistical analysis using freely-available "EZR (Easy R)" software].

Area of Science:

• Biostatistics
• Statistical Computing
• Clinical Research

Context:

• Clinicians require robust statistical analysis for evidence evaluation and study design.
• R is a powerful, free statistical software but lacks an intuitive graphical user interface (GUI).
• Existing GUIs like R commander have limitations, particularly in biostatistics.

Purpose:

• To introduce EZR (Easy R), an enhanced R commander GUI.
• To provide accessible biostatistical functions for clinical research.
• To facilitate learning R script writing and ensure analysis traceability.

Summary:

• EZR integrates advanced statistical functions into an easy-to-use GUI for R.
• It supports complex analyses such as survival analysis with competing risks and time-dependent covariates.
• The software automatically generates R scripts, aiding user learning and analysis reproducibility.

Impact:

• EZR empowers clinicians and researchers to perform sophisticated statistical analyses with point-and-click ease.
• It enhances the quality and transparency of statistical methods in clinical studies.
• Facilitates R script learning, promoting reproducible research and expert supervision.
