Sodium intake and blood pressure (synthetic)

Source: R/data.R

A simplified simulation of the effect of sodium intake on blood pressure, proposed by Luque-Fernandez et al. (2019). Age confounds both the treatment (high sodium intake) and the outcome (blood pressure). The true ATE used in the data generating process is 1.05.

sodium

Format

A data frame with 10,000 rows and 3 columns:

age

Age in years (confounder).

sodium

Binary treatment: high sodium intake (1) or not (0).

bp

Systolic blood pressure (outcome).
