Print league table for network meta-analysis results

A league table is a square matrix showing all pairwise comparisons in a network meta-analysis. Typically, both treatment estimates and confidence intervals are shown.

Usage
netleague(x, y,
          comb.fixed = x$comb.fixed, comb.random = x$comb.random,
          seq = x$seq, ci = TRUE, backtransf = TRUE,
          digits = gs("digits"))
Arguments
x

An object of class netmeta (mandatory).

y

An object of class netmeta (optional).

comb.fixed

A logical indicating whether a league table for fixed effect meta-analyses should be printed.

comb.random

A logical indicating whether a league table for random effects meta-analyses should be printed.

seq

A character or numerical vector specifying the sequence of treatments in rows and columns of a league table.

ci

A logical indicating whether confidence intervals should be shown.

backtransf

A logical indicating whether printed results should be back transformed. If backtransf=TRUE, results for sm="OR" are printed as odds ratios rather than log odds ratios, for example.

digits

Minimal number of significant digits, see print.default.

Details

If argument y is not provided, the league table contains the same information in the lower and upper triangle, i.e., treatment comparisons and confidence intervals for network meta-analysis object x.

If argument y is provided, the league table contains information on treatment comparisons from network meta-analysis object x in the lower triangle and from network meta-analysis object y in the upper triangle.

R function netrank can be used to change the order of rows and columns in the league table (see examples).
