- In Reports added a button to extract an analysis or graph into a separate window
- Added an option to increase the number of decimal places used in reports, see Reports options

- Improved algorithm for identifying data points in graphs.


MedCalc 20.015
- Added an option to slightly shift ("jitter") coincident data points in scatter diagrams so that the markers do not completely overlap. See Applying jitter in scatter diagrams.
- Several other minor improvements.


MedCalc 20.014
- Several minor bug fixes and improvements.


MedCalc 20.013
- Fixed a bug in Logistic regression which caused the regression curve not to be displayed in the graph.


MedCalc 20.010
- Modified report for Cox proportional-hazards regression includes Harrell's C-index with 95% confidence interval.
- Revised layout of Copy graph options and Export graph options
- In Copy graph options, provided an option Also copy in SVG format. Copying graphs in SVG format is recommended when you are using Office 2016 (when all Office updates are installed), Office 2019 or Office 365.
