A Python package for calculating the metrics for diabetes control from CGM and FGM data.
The goal of this project is to enable researchers to quickly calculate the metrics of diabetes control outlined in the Internation consensus on the use of continuous glucose monitors in Python.
The method used for calculating the metrics are all based on the advice given in the consensus.
The diametrics functions are contained within a metrics.py file. The functions are
all_metrics calculates all of the below metrics
average_glucose mean glucose data given
time_in_range % time spent in normal (3.9-10mmol/L), hyperglycaemia (>10) and hypoglycaemia (<3.9). Hyper- and hypo-glycaemia are also broken down to % time in level 1 and level 2
glycemic_variability standard deviation (SD), coefficient of variation (CV) and min and max glucose
ea1c estimated A1c
hypoglycemic_episodes the number of level 1 and level 2 hypoglycemic episodes, plus an optional breakdown of every episode with start and end times
percent_missing percentage of data missing between two timepoints
The functions take Pandas dataframes as the arguments along with the column names for the glucose readings and time. The functions can be used on datasets with only one person's data or can be used on a combined dataframe with an ID column, whose name can be specified if present.
For some of the functions there is an option to switch the thresholds to exercise thresholds, rather than normal ones.
