Glycemic Variability Measures for CGM data

INSTRUCTIONS: Specify details about your uploaded file in the Time Inputs, Glucose Inputs, Calibration Inputs, and Multiple Downloads sections below. Then click on ``Update output''.
If you change something in your file, click Browse again to re-upload it. The data file you upload should be stripped of any identifiers, such as name, medical record number, date of birth, home address, CGM serial number, etc.

Time inputs

Time zero (select one)

Numerical index of time column

Date format (select one)

Time format (select one)

Separator of dates and times

E.g., '2021-02-02T01:32:20' has separator 'T' Do not use quotation marks in your input Enter an underscore if a space is the separator

Glucose inputs

Numerical index of glucose column

How does the CGM record values that are above detection?

Set such high glucose values to this

How does the CGM record values that are below detection?

Set such low glucose values to this

Calibration inputs

Numerical index of calibration column, if present

How does the CGM record values that were used for calibration only?

Multiple downloads

Your file may contain multiple downloads from the same CGM. The app will not handle downloads that cover overlapping time periods; remove any overlapping rows before uploading.
