summary.ce {hesim} | R Documentation |
Summary method for cost-effectiveness object
Description
Summarize a ce
object by producing confidence intervals for quality-adjusted
life-years (QALYs) and each cost category with summary.ce()
and format for
pretty printing with format.summary.ce()
.
Usage
## S3 method for class 'ce'
summary(object, prob = 0.95, labels = NULL, ...)
## S3 method for class 'summary.ce'
format(
x,
digits_qalys = 2,
digits_costs = 0,
dr_qalys = NULL,
dr_costs = NULL,
pivot_from = "strategy",
drop_grp = TRUE,
pretty_names = TRUE,
...
)
Arguments
object |
A |
prob |
A numeric scalar in the interval |
labels |
A list of named vectors containing the values and labels of
variables. The elements of each vector are the values of a variable and the
names are the labels. The names of the list are the names of the variables.

Value
summary.ce()
returns an object of class summary.ce
that is a tidy
data.table
with the following columns:
- dr
The discount rate.
- strategy
The treatment strategy.
- grp
The patient subgroup.
- type
Either
"QALYs"
or"Costs"
.- category
Category is always
"QALYs"
whentype == "QALYs"
; otherwise, it is the cost category.- estimate
The point estimate computed as the average across the PSA samples.
- lower
The lower limit of the confidence interval.
- upper
The upper limit of the confidence interval.
format.summary.ce()
formats the table according to the arguments passed.
