print(x, ...)

Arguments

x: an nhanes_design object
...: currently not used

Value

the design object, invisibly.

Examples

library(cardioStatsUSA)

ds <- nhanes_design(data = nhanes_data,
                    key = nhanes_key, 
                    time_values = 'most_recent',
                    outcome_variable = 'bp_sys_mean')

print(ds)

## -------------------------------- NHANES design --------------------------------
## 
## Outcome variable: bp_sys_mean
## - label: Systolic blood pressure (SBP), mm Hg
## - type: continuous
## - description: Mean systolic blood pressure in mm Hg. This is based on the
##     average of up to 3 readings. Participants were required to have at least one
##     reading. Overall, >95% of participants with at least one systolic blood
##     pressure reading had three readings.  From 1999-2000 through 2015-2016,
##     systolic blood pressure was measured using a mercury sphygmomanometer.  In
##     2017-2020, systolic blood pressure was measured using an oscillometric device.
##     The systolic blood pressure in 2017-2020 was calibrated to the mercury device
##     by adding 1.5 mm Hg to the mean measured oscillometric value.
## 
## Group variable: None
## Stratify variable: None

## N observations
