ligvp: lability index

Description

Lability index is a measure of glycemic variability that evaluates the metabolic lability and its possible improvement in patients candidates for islet transplantation.

Usage

ligvp(x, t = 24, ts = 5)

Value

A data frame containing the li values.

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.

ts

Numeric value with sampling time of glucose values. Permitted values are 5 and 15 minutes. Default value of 5 minutes.
