To be more useful in larger studies, the tool can compare six ROC curves in various ways. The app also features advanced ROC curve analysis capabilities, enabling the creation of a ROC curve graph with 95% confidence bounds and added information of specificity, sensitivity, predictive values, likelihood ratios, conclusive plots, and more. Tools for managing diagrams are available with a single click and include comparisons, scatter plots, subgroup graphs, support for up to 24 continuous variables, and much more). The app has support for over 100 thousand spreadsheet rows, tools for sorting, filtering, and editing, and a built-in browser for managing all the data captured in the research studies. As of today, this MedCalc represents one of the most popular biomedical research tools for statistical analysis of large datasets, curve analysis, data plotting, Bablok, and Deming regression, and more. Originally released to the public in 1993 as a DOS-only app, MedCalc received constant upgrades, eventually moving to the Windows-only space a few years later. In its core, MedCalc hosts support for basic parametric and non-parametric statistical procedures, tools for meta-analysis and sample size calculations, and a wide array of graph outputs (descriptive statistics, non-linear regression, logistic regressions, ANOVA, Mann–Whitney test, Wilcoxon test, χ2 test, correlation) and more.
With built-in spreadsheet support as an input data, it can easily import data from other spreadsheet apps and formats ( Excel, SPSS, Dbase, Lotus, SYLK, DIF, or even extracted from TXT files) and thus be more easily integrated into various research and education initiatives performed all around the world. MedCalc is an advanced statistical software package built from the ground up to serve the needs of biomedical science researchers.
