'Wald confidence interval in gtsummary
Is there a way to specify the method of calculating confidence interval in gtsummary. Am asking this because of some inconsistencies with profile confidence intervals by confint fuction.
Have a look at the pvalues and CIs of var1 and var2 below:
library(tidyverse)
library(gtsummary)
set.seed(2021)
testdata <- tibble(
var1 = rbinom(1114, 1, 0.12),
var2 = rbinom(1114, 1, 0.82),
var3 = rbinom(1114, 1, 0.60),
var4 = rbinom(1114, 1, 0.18),
var5 = rbinom(1114, 1, 0.12),
var6 = rbinom(1114, 1, 0.05),
var7 = rbinom(1114, 1, 0.63),
var8 = rbinom(1114, 1, 0.20),
var9 = rbinom(1114, 1, 0.06),
var10 = rbinom(1114, 1, 0.40),
var11 = rbinom(1114, 1, 0.35),
var12 = rbinom(1114, 1, 0.32),
outcome = rbinom(1114, 1, 0.04)
) %>%
mutate(across(.cols = everything(),
~factor(., levels = c(0, 1),
labels = c("No", "Yes"))))
mvariate.regress <- function(outcome, covariates, mydata) {
form <- paste(outcome, "~",
paste(covariates, collapse = " + "))
model1 <- glm(as.formula(form),
data = mydata, family = binomial)
model1
}
ipvars <- paste0("var", 1:12)
mlogitfit <- mvariate.regress("outcome", ipvars, testdata)
mlogitfit %>%
tbl_regression(
exponentiate = TRUE
) %>%
bold_p() %>%
bold_p(t = 0.05) %>%
bold_labels() %>%
modify_header(label = "**Variable**",
estimate = "**adjusted OR**") %>%
modify_table_styling(
columns = c("ci", "estimate"),
rows = reference_row %in% TRUE,
missing_symbol = "Ref"
)
I would get the desired results if I were to use confint.default function
