Graphics and statistics for cardiology: survival analysis.

Area of Science:

• Biostatistics
• Medical Informatics
• Clinical Epidemiology

Background:

• Medical literature reporting frequently omits crucial data for evaluating study validity and generalizability.
• Existing reporting guidelines over the past two decades have not adequately addressed survival data specifics.
• There is a need for standardized reporting practices for survival data to improve scientific rigor.

Purpose of the Study:

• To provide specific recommendations for the tabular and graphical representation of survival data.
• To advocate for the release of data and analytical software to foster reproducible research.
• To enhance the transparency and replicability of clinical studies utilizing survival analysis.

Main Methods:

• Review of existing reporting standards and guidelines in medical literature.
• Development of recommendations for presenting survival data in tables.
• Formulation of guidelines for graphical displays of survival data.
• Argument for the open sharing of datasets and statistical software.

Main Results:

• Specific recommendations for tabular formats of survival data are proposed.
• Guidelines for creating informative graphical representations of survival data are outlined.
• The importance of data and software availability for ensuring reproducible survival analyses is emphasized.

Conclusions:

• Implementing these recommendations can improve the quality and interpretability of survival data reporting.
• Making data and analytic software accessible is crucial for advancing reproducible medical research.
• Standardized reporting of survival data will enhance the reliability and generalizability of findings in clinical studies.
