calculate_cad2_2012_basic_ptp: Calculate 2012 CAD2 Basic PTP for obstructive CAD

Description

This function returns a patient's pre-test probability (PTP) of obstructive coronary artery disease based on the 2012 CAD Consortium 2 (CAD2) basic model.

Usage

calculate_cad2_2012_basic_ptp(
  age,
  sex,
  chest_pain_type,
  label_sex_male = c("male"),
  label_sex_female = c("female"),
  label_sex_unknown = c(NA, NaN),
  label_cpt_nonanginal = c("nonanginal"),
  label_cpt_atypical = c("atypical"),
  label_cpt_typical = c("typical"),
  label_cpt_unknown = c(NA, NaN)
)

Value

Arguments

age

Input numeric value to indicate the age of the patient in years.

sex

The value of variable in the parameters label_sex_male, label_sex_female and label_sex_unknown.

chest_pain_type

The value of variable in the parameters, label_cpt_nonanginal, label_cpt_atypical, label_cpt_typical and label_cpt_unknown.
