Compute "Blood Pressure [Youth] (Systolic): Number missing"

Computes the summary score ph_y_bp__sys_nm Blood Pressure [Youth] (Systolic): Number missing

• Summarized variables:

  • ph_y_bp__sys__r01_001

  • ph_y_bp__sys__r01_002

  • ph_y_bp__sys__r01_003

  • ph_y_bp__sys__r02_001

  • ph_y_bp__sys__r02_002

  • ph_y_bp__sys__r03_001

  • ph_y_bp__sys__r03_002

Calculation

There are at most 3 possible rounds of measurements, and the calculation is as follows:

• if round 3 is available, use it, otherwise use round 2, otherwise use round 1

• for round 3 and 2, there are at most 2 measurements

• for round 1, there are at most 3 measurements:

  • participants with 3 measurements, and 0 missing, nm = 0

  • participants with 2 measurements, and 1 missing, nm = 1 - 1 = 0

  • participants with 1 measurement, and 2 missing, nm = 2 - 1 = 1

  • participants with 0 measurements, and 3 missing, nm = 3 - 1 = 2

Usage

compute_ph_y_bp__sys_nm(data, name = "ph_y_bp__sys_nm", combine = TRUE)

Arguments

data

tbl, Dataframe containing the columns to be summarized.

name

character, Name of the new column to be created. Default is the name in description, but users can change it.

combine

logical, If TRUE, the summary score will be appended to the input data frame. If FALSE, the summary score will be returned as a separate data frame.

Value

tbl. The input data frame with the summary score appended as a new column.
