An object of class netmeta.
A logical indicating whether results for the fixed effects (common effects) model should be printed.
A logical indicating whether results for the random effects model should be printed.
A logical indicating whether prediction intervals should be printed.
Reference treatment.
A logical indicating whether results
should be expressed as comparisons of other treatments versus the
reference treatment (default) or vice versa. This argument is
only considered if reference.group has been specified.
A logical or "NULL". If TRUE,
matrices with all treatment effects, and confidence limits will
be printed.
Additional arguments.
An object of class summary.netmeta.
A logical indicating whether results should be
back transformed in printouts and forest plots. If
backtransf = TRUE, results for sm = "OR" are
presented as odds ratios rather than log odds ratios, for
example.
A numeric defining the minimum number of characters used to create unique treatment names.
A logical indicating whether information on title of meta-analysis, comparison and outcome should be printed at the beginning of the printout.
Minimal number of significant digits, see
print.default.
Minimal number of significant digits for tests
of overall effect, see print.default.
Minimal number of significant digits for p-value
of overall effects, see print.default.
Minimal number of significant digits for
p-value of heterogeneity tests, see print.default.
Minimal number of significant digits for
heterogeneity statistics, see print.default.
Minimal number of significant digits for
between-study variance, see print.default.
Minimal number of significant digits for square
root of between-study variance, see print.default.
Minimal number of significant digits for I-squared
statistic, see print.default.
A logical specifying whether p-values should be printed in scientific notation, e.g., 1.2345e-01 instead of 0.12345.
A character used as thousands separator.
Text printed to identify between-study variance \(\tau^2\).
Text printed to identify \(\tau\), the square root of the between-study variance \(\tau^2\).
Text printed to identify heterogeneity statistic I\(^2\).
A logical indicating whether a legend should be printed.
A list is returned with the following elements:
Results for pairwise comparisons (data frame with columns studlab, treat1, treat2, TE, seTE, lower, upper, z, p).
Results for pairwise comparisons based on fixed effects model (data frame with columns studlab, treat1, treat2, TE, seTE, lower, upper, z, p, leverage).
Results for pairwise comparisons based on random effects model (data frame with columns studlab, treat1, treat2, TE, seTE, lower, upper, z, p).
Results for fixed effects model (a list with elements TE, seTE, lower, upper, z, p).
Results for random effects model (a list with elements TE, seTE, lower, upper, z, p).
Prediction intervals (a list with elements seTE, lower, upper).
Study labels coerced into a factor with its levels sorted alphabetically.
Number of arms for each study.
Total number of studies.
Total number of pairwise comparisons.
Total number of treatments.
Total number of designs (corresponding to the unique set of treatments compared within studies).
Overall heterogeneity / inconsistency statistic.
Degrees of freedom for test of heterogeneity / inconsistency.
P-value for test of heterogeneity / inconsistency.
I-squared, lower and upper confidence limits.
Square-root of between-study variance.
Overall heterogeneity statistic.
Degrees of freedom for test of overall heterogeneity.
P-value for test of overall heterogeneity.
Overall inconsistency statistic.
Degrees of freedom for test of overall inconsistency.
P-value for test of overall inconsistency.
A character string indicating underlying summary measure.
A character string indicating which method is to be used for pooling of studies.
The level used to calculate confidence intervals for individual studies.
The level used to calculate confidence intervals for pooled estimates.
As defined above.

As defined above.
Label for confidence interval.
A character specifying the sequence of treatments.
An optional value for the square-root of the between-study variance \(\tau^2\).
A character used in comparison names as separator between treatment labels.
A numeric defining the minimum number of characters used to create unique treatment names.
Title of meta-analysis / systematic review.
