IScalc

IScalc bundles popular insulin sensitivity indexes, so you don't need an extra excel sheet or to copy paste a function.

You can install it with

# install.packages("devtools")
devtools::install_github("jcpsantiago/IScalc")

Indexes

Comparisons between each index and the hyperinsulinaemic-euglycaemic clamp are discussed in Otten et al., 2014

Fasting indices:

• FIRI
• HOMA-IR
• QUICKI (both original and revised)

OGTT indices:

• Cederholm
• Gutt (ISI_0,120)
• Matsuda (Composite Index)
• NEFA-ISI
• Stumvoll-ISI
• Stumvoll-MCR

TODO

• Implement OGIS.
• Reimplement the functions using switch
