hisayama: 10-year risk calculation for ASCVD events based on the Hisayama study

Description

hisayama() calculates the 10-year probability of developing the first atherosclerotic cardiovascular disease (ASCVD) event. Mandatory variables: "age", "male", "sbp", "t2dm", "hdl", "ldl", "urineprotein", "smoking", "exercise". These variables must be applied with the above spelling.

The details of this prediction model should be referred to the original article. "Development and Validation of a Risk Prediction Model for Atherosclerotic Cardiovascular Disease in Japanese Adults: The Hisayama Study"

Usage

hisayama(data)

Value

Based on the mandatory variables, a risk probability will be calculated for each line. The primary cautions are as follows,

1."Data frame must contain the following columns.":

If you contact this warning message, the data frame did not contain required variables. Please check the data frame contain the mandatory variables in the designated spelling.

2."Data frame contains NA values in required columns.":

hisayama() returns the NA if the required variables were missing, or NAs were generated in the calculation process.

3."Some individuals are aged 80 or older. results may not be accurate.":

4."Some individuals are aged 40 or younger. results may not be accurate.":

This risk prediction model was developed based on the Hisayama study participants(older than 40 and younger than 80). In the calculation process, when the participants' age is outside of the range, the result is returned as follows.

1. Younger than 30: same value for 30-40.

2. Older than 80: same value for 75-79.

Arguments

data

A data frame containing the variables to estimate risk.

Examples

data <- data.frame(
  age = c(45, 55, 90),
  male = c(1, 0, 1),
  sbp = c(120, 130, 145),
  t2dm = c(0, 1, 0),
  hdl = c(55, 45, 35),
  ldl = c(110, 130, 160),
  urineprotein = c(NA, 1, 0),
  smoking = c(0, 1, 0),
  exercise = c(1, 0, 1)
)
