print.netmeta: Print and summary method for objects of class netmeta

Description

Print and summary method for objects of class netmeta.

Usage

## S3 method for class 'netmeta':
print(x, sortvar, level=x$level, level.comb=x$level.comb,
      comb.fixed=x$comb.fixed, comb.random=x$comb.random,
      reference.group=x$reference.group, all.treatments=x$all.treatments,
      details=TRUE, ma=TRUE, logscale=FALSE,
      digits=max(4, .Options$digits - 3), ...)
## S3 method for class 'netmeta':
summary(object,
        level=object$level, level.comb=object$level.comb,
        comb.fixed=object$comb.fixed, comb.random=object$comb.random,
        reference.group=object$reference.group, all.treatments=object$all.treatments,
        warn=object$warn, ...)
## S3 method for class 'summary.netmeta':
print(x, comb.fixed=x$comb.fixed, comb.random=x$comb.random,
      reference.group=x$reference.group, all.treatments=x$all.treatments,
      logscale=FALSE, header=TRUE, digits=max(3, .Options$digits - 3), ...)

Arguments

x
An object of class netmeta or summary.netmeta.
object
An object of class netmeta.
sortvar
An optional vector used to sort individual studies (must be of same length as x$TE).
level
The level used to calculate confidence intervals for individual studies.
level.comb
The level used to calculate confidence intervals for pooled estimates.
comb.fixed
A logical indicating whether a fixed effect meta-analysis should be conducted.
comb.random
A logical indicating whether a random effects meta-analysis should be conducted.
reference.group
Reference group.
all.treatments
A logical or value "NULL". If TRUE, matrices with all treatment effects, and confidence limits will be printed.
details
A logical indicating whether further details for individual studies should be printed.
ma
A logical indicating whether summary results of meta-analysis should be printed.
logscale
A logical indicating whether results for summary measures 'RR', 'OR', 'HR', or 'PLN' will be printed on logarithmic scale.
header
A logical indicating whether information on title of meta-analysis, comparison and outcome should be printed at the beginning of the printout.
digits
Minimal number of significant digits, see print.default.
warn
A logical indicating whether the use of summary.meta in connection with metacum or metainf should result in a warning.
...
Additional arguments.
