This application calculates different glucose variability measures, including average measures of glycemia, measures of glycemic variability, and measures of glycemic risk, from continuous glucose monitoring data obtained from diabetic patients.
Made with R package gluvarpro.
The application is divided into five parts or sections:
There are two ways of loading data. The user can load their own data or can load three examples from the package.
The user can fill empty values with two different functions: linear or cubic splines; and can select the maximum interval to fill the empty values.
The application shows the number of observations included in the data, the number of days, the range of glucose values and the number of empty values.
The application represents the data as time series where the X axis represents the time and the Y axis the glycemia values in mg/dl.
The user can select the color for plotting data points. If the data-set contains more than one day, different colors can be selected for each day of data.
The application calculates the following average measures of glycemia:
The application calculates the following glycemic variability measures:
The user can select the interval to calculate the measures and the sampling time of the data.
The measures are represented by graphs in each tab panel. If data-set contains more than one day, different colors can be selected for each day of data.
The user can select different parameters to evaluate the measures:
The application shows two different tables. The first one is a table with variability measures for each data point. The second one shows the mean values of the measures for each day along with four different deviations:
The application shows the analysis of results based on the mean values of the measures for each day.
The application can generate a pdf file with the results of the mean values of the different glycemic variability measures, along with the deviations, plus the parameters selected by the user.
In addition, it allows the generation of two csv files with the same data that appears in the Glycemic Variability Tables section.
We recommend you try all these features here!!
