Unit

OR per yes/no visible dampness and/or mold or mold odor

Formula

  • Generates random samples of possible ORs.
    • Normal distribution assumed, sd estimated from confidence interval using sd = (upper bound - lower bound)/3.92
n <- 10000
erf <- rnorm(n, 1.56, (1.86-1.30)/3.92)
dim(erf) <- c(n, 1, 1)
dimnames(erf) <- list(obs=1:n, Outcome="Current asthma", "Age"="All")
erf <- as.data.frame(as.table(erf))

Result

{{#opasnet_base_link:Op_en4716}}
