Function netgraph:
- complete rewrite of this function (without changing previous default
settings substantially)
- list of major new features:
- additional layouts beside circular presentation (see argument
'start.layout')
- implementation of stress majorization algorithm to optimize layout
(argument 'iterate')
- additional methods to determine width of lines connecting
treatments (argument 'thickness')
- highlight multi-arm studies (arguments 'multiarm' and
'col.multiarm')
- possibility to provide a neighborhood matrix to specify
neighborhood differently than using the adjacency matrix, for
example content-based (argument 'N.matrix')
- possibility to provide x- and y-coordinates for network plot
(arguments 'xpos' and 'ypos')
Function netmeta:
- calculate treatment estimates from all direct pairwise treatment
comparisons (both fixed effect and random effects model)
- new list components:
'tau.preset', 'TE.direct.fixed', 'seTE.direct.fixed',
'lower.direct.fixed', 'upper.direct.fixed', 'zval.direct.fixed',
'pval.direct.fixed', 'TE.direct.random', 'seTE.direct.random',
'lower.direct.random', 'upper.direct.random', 'zval.direct.random',
'pval.direct.random'
Function nma.ruecker (used internally)
- changed accordingly to reflect changes in netmeta function
Function forest.netmeta:
- new argument sortvar (default: sort treatment effect estimates
according to list component 'seq' of netmeta object)
New functions stress and nodedist (used internally)
- auxiliary functions for netgraph function
Help pages updated accordingly
2014-06-24, version 0.5-0
Functions nma.krahn, netmeasures, netheat, decomp.design, and
print.decomp.design:
- random effects network meta-analysis added
Function netheat:
- new argument 'random'
Functions nma.krahn, decomp.design, and netheat:
- new argument 'tau.preset'
Function decomp.design:
- correct design-specific decomposition of Q statistic in network
meta-analysis with multi-arm studies
- list component 'Q.design' renamed to 'Q.het.design'
- list component 'Q.detach' renamed to 'Q.inc.detach'
- list component 'residuals' renamed to 'residuals.inc.detach'
- new list components:
'Q.inc.random', 'Q.inc.random.preset',
'Q.inc.design.random.preset', 'residuals.inc.detach.random.preset',
'tau.preset'
New functions tau.within and decomp.tau (used internally)
Help pages updated accordingly
2014-05-27, version 0.4-4
Functions netmeta and nma.ruecker:
- modified such that the estimated tau-squared in random effects model
considers multi-arm studies
Function print.netmeta:
- information on percentage weight not printed as interpretation is
difficult
Dataset Senn2013:
- use of unpooled standard error for each treatment comparison
2014-04-14, version 0.4-3
Function netmeta:
- numeric values for arguments 'treat1' and 'treat2' not converted to
character values (only factors converted to characters)
- check whether treatments are different (arguments 'treat1' and
'treat2')
Function print.summary.netmeta:
- print random effects estimates according to argument 'seq'
Function forest.netmeta:
- sort treatment effect estimates according to argument 'seq'
Function nma.ruecker (used internally):
- changed such that all treatment effects are calculated irregardless
of treatment order (some treatment effects remained NA depending on
order of treatments)
2014-03-31, version 0.4-2
Function netmeasures:
- bug fix using correct formula to calculate direct evidence
proportion (variance instead of standard error)
2014-03-21, version 0.4-1
Function netmeta:
- Argument 'seq' added (see also R function netgraph)
Function netgraph:
- new default for argument 'seq'
Help pages updated accordingly
Some internal code cleaning to improve readability of R functions
2014-03-07, version 0.4-0
New functions added:
- netgraph (network graph)
- netheat (net heat graph)
- netmeasures (measures for network meta-analysis)
- decomp.design (design-based decomposition of Cochran's Q)
- print.decomp.design (corresponding print function)
- p.ci, format.TE, nma.krahn, nma.ruecker (used internally)
Function netmeta:
- Check added whether all pairwise comparisons are provided for
multi-arm studies
Help pages added for new functions
Help page of function netmeta updated
2013-08-01, version 0.3-1
Functions netmeta and summary.netmeta:
- new list component n (number of treatments)
Function print.summary.netmeta:
- modified such that number of treatments is printed
- modified such that argument 'reference.group' works as expected for
random effects model
