Ploticus: Clinical Trials Examples


This page gathers together a number of examples related to data management in clinical trials. Ploticus was written at a clinical trials data collection/analysis center. Many of these examples are based on data displays that Ploticus has been used for in real projects; however unless noted in the example script, the data have been fictionalized.
