Question

What are exposure-response functions to vitamins?

Answer

+ Show code - Hide code

#This is code Op_en6866/ on page [[ERFs of vitamins]]

library(OpasnetUtils)
objects.latest("Op_en6866", code_name="initiate")
ERF_vit <- EvalOutput(ERF_vit)
threshold_vit <- EvalOutput(threshold_vit)

cat("ERF_vit\n")
oprint(summary(ERF_vit))
cat("threshold_vit\n")
oprint(summary(threshold_vit))

Rationale

Data

Response metric: 1 if the recommendation is not met, 0 if it is met.
