.- 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.

Results for pairwise comparisons based on fixed effect model (a list with elements TE, seTE, lower, upper, z, p, level, df, studlab, treat1, treat2, leverage).

Results for pairwise comparisons based on random effects model (a list with elements TE, seTE, lower, upper, z, p, level, df, studlab, treat1, treat2).

Results for fixed effect model (a list with elements TE, seTE, lower, upper, z, p, level, df).

Results for random effects model (a list with elements TE, seTE, lower, upper, z, p, level, df).
