pstrgvp: percentage spent below/above the target range

In gluvarpro: Glucose Variability Measures from Continuous Glucose Monitoring Data

percentage spent below/above the target range

Description

Percentage spent below/above the target range is an average measure of glycemia that calculates the percentage of average time that the patient is in hypoglycemic and hyperglycemic ranges. This measure calculates the time-in-range measure (npstr) but does not give more weight to extremely low values (lpstr) nor to high values (hpstr). Arbitrary target range may not be optimal, so the ranges must to be chosen careful.

Usage

pstrgvp(x, t = 24, tdown = 70, tup = 180)

Arguments

x	Data-set with data frame format containing three columns: date: date of the observation with format yyyy/mm/dd. time: time of the observation with 24 hour format hh:mm:ss. glucose: glucose value of the observation in [mg/dl].
t	Numeric value with interval for calculating the measurement. Permitted values are 4, 6, 8, 12 and 24 hours. Default value of 24 hours.
tdown	Numeric value with target range low. Default value of 70 [mg/dl].
tup	Numeric value with target range high. Default value of 180 [mg/dl].

Value

A data frame containing the lpstr, hpstr, npstr and pstr values.
