Software Overview

MedCalc provides a Windows-based environment for statistical analysis with features tailored to biomedical researchers. Its data management tools allow researchers to organize large datasets, handle missing values, exclude outliers, and select specific subgroups for statistical procedures.
The software includes specialized statistical methods for diagnostic and method comparison studies, together with graphing tools that can be used to visualize results and export figures for reports or presentations.

Key Features

• Statistical analysis tools designed for biomedical research.
  
• Integrated spreadsheet with 1,048,576 rows and 16,384 columns.
  
• Handling of missing data.
  
• Easy exclusion of outliers.
  
• Built-in WYSIWYG text editor.
  
• Import support for Excel, Excel 2007, SPSS, DBase, and Lotus files.
  
• Import support for SYLK, DIF, and plain text formats.
  
• Subgroup selection for statistical analysis.
  
• Receiver Operating Characteristic (ROC) curve analysis.
  
• Bland-Altman analysis for method comparison studies.
  
• Passing-Bablok regression.
  
• Deming regression.
  
• Graph creation and editing tools.
  
• Graph data-point identification.
  
• Export of graphs to common image formats and PowerPoint slides.
  

ROC Curve Analysis

MedCalc provides dedicated tools for Receiver Operating Characteristic curve analysis. The ROC module can compare up to six ROC curves and calculate diagnostic performance measures for different threshold values.
The analysis includes Area Under the Curve (AUC), standard error, 95% confidence intervals, and P-values, with options based on the methodologies of DeLong et al. and Hanley & McNeil.

• Sensitivity, specificity, likelihood ratios, and positive and negative predictive values for possible threshold values.
  
• ROC curve graphs with 95% confidence bounds.
  
• Interactive selection of threshold values with corresponding sensitivity and specificity calculations.
  
• Plots of sensitivity and specificity or cost against criterion values.
  
• Plots of predictive values against prevalence.
  
• Interval likelihood ratios.
  
• Comparison of up to six ROC curves, including differences between their areas under the curves.
  
• Sample size calculations for ROC curve area and ROC curve comparisons.
  

Data Management

The integrated spreadsheet provides a large workspace for biomedical datasets and includes support for handling missing information. Outliers can be excluded when required, while subgroup selection allows specific portions of a dataset to be used for statistical analysis.
MedCalc can import information from Excel, Excel 2007, SPSS, DBase, Lotus, SYLK, DIF, and plain text files, providing several options for bringing existing research data into the application.

Graphs and Visualization

MedCalc includes a range of graphing functions for presenting statistical results. Data points can be identified directly in graphs, while text boxes, lines, arrows, and connectors can be added to graphical output.
Graphs and statistical results can be named, saved, and recalled. Graphs can be exported as SVG, PNG, JPG, GIF, BMP, PCX, or high-resolution TIF files, or saved as PowerPoint slides in PPTX format.

Documentation

The software provides context-sensitive help, dialog-box assistance, and access to a complete HTML manual on the MedCalc website. A paperback manual is also provided as part of the available documentation resources.

System Requirements
