MedCalc is a complete statistical program

MedCalc is the most user-friendly software forReceiver Operating Characteristic curve (ROC curves) analysis. The MedCalc ROC module includes comparison of up to 6 ROC curves.The software includes Bland & Altman plot,Passing and Bablok and Deming regression and many other procedures for method comparison studies and laboratory method evaluation.

Create ROC curves easily

MedCalc allows to perform ROC curve analysis easily and accurately. Our ROC curve analysis module includes:

• Area under the curve (AUC) with standard error (SE) and 95% confidence interval (CI). The standard error can be calculated using 2 methods:
  • DeLong et al. (1988)
  • Hanley & McNeil (1982)
  The Confidence Interval for the AUC can be calculated using the following methods:
  • Binomial exact confidence interval
  • AUC ± 1.96 its Standard Error.
• Calculate optimal criterion value taking into account costs: option to calculate the optimal criterion value taking into account the disease prevalence and cost of false and true positive and negative decisions (Zweig & Campbell, 1993).
• Calculation of Youden index.
• ROC curve graph with 95% Confidence Bounds.
• Plot of sensitivity and specificity versus criterion values.
• Interval likelihood ratios.
• Sample size calculation for area under ROC curve and comparison of ROC curves.

MedCalc creates a list of sensitivity, specificity, likelihood ratios, and positive and negative predictive values for all possible threshold values.

Threshold values can be selected in an interactive dot diagram with automatic calculation of corresponding sensitivity and specificity.

Advanced options

MedCalc offers the following unique advanced options:

• Estimation of sensitivity and specificity at fixed specificity and sensitivity: an option to compile a table with estimation of sensitivity and specificity (with a BCa bootstrapped 95% confidence interval) for a fixed and prespecified specificity and sensitivity of 80%, 90%, 95% and 97.5% (Zhou et al., 2002).
• Bootstrap Youden index confidence interval: an option to calculate a BCa bootstrapped 95% confidence interval (Efron & Tibshirani, 1994) for the Youden index and its associated criterion value.

These options require bootstrapping which is a computationally intensive and sometimes time consuming technique.

Comparison of ROC curves

• MedCalc can compare up to 6 ROC curves with the method of DeLong et al. (1988) or Hanley & McNeil (1983). The software gives the difference between the areas under the ROC curves, with standard error, 95% confidence interval and P-value.

Method comparison, method evaluation and agreement

Method comparison & evaluation

MedCalc contains the following statistical procedures specifically for Method comparison & evaluation:

• Bland & Altman plot
• Bland-Altman plot with multiple measurements per subject
• Mountain plot
• Deming regression
• Passing & Bablok regression
• Coefficient of variation from duplicate measurements

Agreement & responsiveness

For analyzing agreement and responsiveness, MedCalc offers:

• Intraclass correlation coefficient
• Concordance correlation coefficient
• Inter-rater agreement (kappa)
• Cronbach’s alpha
• Responsiveness

ROC curve analysis

MedCalc is the most commonly used software for ROC curve analysis in biomedical literature. See:ROC curve analysis features of MedCalc and MedCalc manual: ROC curve analysis.

Reference interval

MedCalc calculates reference intervals using the Normal distribution, a non-parametrical percentile method, and optionally a robust method as described in the CLSI Guidelines C28-A3.See MedCalc manual: Reference interval

Control chart

The control chart is a graph used to study how processes or measurements change over time with data plotted in time order. Rules are applied (Westgard et al., 1981) to automatically SIGNALwhen the process is out of control.See MedCalc manual: Control chart

Youden plot

The Youden plot is a graphical method to analyse inter-laboratory data, where all laboratories have analysed 2 samples. The plot visualises within-laboratory variability as well as between-laboratory variability.MedCalc draws the original Youden plot and common variations, including an adaptation for non-comparable samples.See MedCalc manual: Youden plot

MedCalc compatibility

MedCalc is compatible with all 32-bit and 64-bit Windows versions starting with WINDOWS XP(with Service Pack 3).

It has obtained the official “Compatible with” Windows Vista, WINDOWS 7 and Windows 8 logo from Microsoft.

Software with the Compatible with Windows logo is certified to be virus free, to install and uninstall cleanly, and to integrate seamlessly in Windows.

Open Source Clinical Trial Software? Cool!

OpenClinica is the world’s leading open source clinical trials software for electronic data capture (EDC) and clinical data management (CDM).

We all know clinical research is complicated. OpenClinica was born out of frustration with existing proprietary electronic data capture (EDC) software that was inflexible, expensive, and difficult to consume. OpenClinica solves these problems by giving you: A way to quickly deploy powerful software for running your clinical study regardless of the study’s size, scope, language, budget, and other factors. The freedom from becoming locked-in to a single vendor The freedom to tailor your EDC solution to your particular needs. OpenClinica allows you to control your eclinical technology, rather than your eclinical technology controlling you. OpenClinica’s commercial open source model  produces enterprise-quality electronic data capture software that is regulatory compliant, technically robust, highly accessible, and easily extensible. It is the product of internally- and community-developed open source software and leading, non-proprietary open standards. What is Open Source? Open source is a type of software license that allows people to freely review, modify, and distribute an application’s underlying source code. Chances are, you already use open source. If you have ever used an Android smartphone, Firefox web browser, the Mac operating system, Google, Amazon.com, or Facebook, you have used open source! There are many different “flavors” of open source licenses. OpenClinica uses theLGPL (Lesser General Public License) which is one of the most widely used open source licenses. Large communities form around successful open source projects, making the software oftentimes far more secure and better performing that their proprietary alternatives. With many developers constantly scrutinizing an application’s underlying source code, it’s hard for bugs to hide. Since the code is shared among numerous parties, it is typically well structured, avoiding the spaghetti-code syndrome that often arises when a single company develops a complex codebase. Open Source and Open Standards Data standards provide uniform ways to represent information or processes according to a detailed specification. A standard is “open” when it is not encumbered by patent, cost, or usage restrictions. Open Source Software (OSS) is defined loosely as software that allows programmers to openly read, redistribute, and modify the source code of that software. The combination of OSS and open standards is a proven way to deliver enhanced flexibility, quality, and efficiency. The OSS development and licensing model encourages experimentation, reduces “reinvention of the wheel,” and allows otherwise unaffiliated parties to build on the work of others. Standards do the same thing. The result is that standards-based OSS is a key driver of increased IT efficiency and a way to wring out unnecessary costs.
