Please use tbl_survfit.
Function takes a `survfit`

object as an argument, and provides a
formatted summary of the results

```
tbl_survival(x, ...)
# S3 method for survfit
tbl_survival(
x,
times = NULL,
probs = NULL,
label = ifelse(is.null(probs), "{time}", "{prob*100}%"),
level_label = "{level}, N = {n}",
header_label = NULL,
header_estimate = NULL,
failure = FALSE,
missing = "-",
estimate_fun = NULL,
...
)
```

## Arguments

- x
A survfit object with a no stratification
(e.g. `survfit(Surv(ttdeath, death) ~ 1, trial)`

), or a single stratifying
variable (e.g. `survfit(Surv(ttdeath, death) ~ trt, trial)`

)

- ...
Not used

- times
Numeric vector of times for which to return survival probabilities.

- probs
Numeric vector of probabilities with values in (0,1)
specifying the survival quantiles to return

- label
String defining the label shown for the time or prob column.
Default is `"{time}"`

or `"{prob*100}%"`

. The input uses glue::glue notation to
convert the string into a label. A common label may be `"{time} Months"`

, which
would resolve to "6 Months" or "12 Months" depending on specified `times`

.

- level_label
Used when survival results are stratified.
It is a string defining the label shown. The input uses
glue::glue notation to convert the string into a label.
The default is `"{level}, N = {n}"`

. Other information available to
call are `'{n}'`

, `'{level}'`

, `'{n.event.tot}'`

, `'{n.event.strata}'`

, and
`'{strata}'`

. See below for details.

- header_label
String to be displayed as column header.
Default is `'**Time**'`

when `time`

is specified, and
`'**Quantile**'`

when `probs`

is specified.

- header_estimate
String to be displayed as column header of the Kaplan-Meier
estimate. Default is `'**Probability**'`

when `time`

is specified, and
`'**Time**'`

when `probs`

is specified.

- failure
Calculate failure probabilities rather than survival probabilities.
Default is `FALSE`

. Does NOT apply to survival quantile requests

- missing
String indicating what to replace missing confidence
limits with in output. Default is `missing = "-"`

- estimate_fun
Function used to format the estimate and confidence
limits. The default is `style_percent(x, symbol = TRUE)`

for survival
probabilities, and
`style_sigfig(x, digits = 3)`

for time estimates.
