Forest plot data for relative risk

Prepare Forest plot data for relative risk

prepare_relative_risk_data(
  data,
  change_ref = c("Y", "N"),
  ci_method = c("Supplied", "Calculated")
)

Arguments

data

(data.frame) Effects table

change_ref

Change reference group ("Y" or "N)

ci_method

(character) confidence interval method, either Supplied (taken from the effect table) or Calculated (calculated within the program).

Value

data frame for specified type of analysis
