Restruscture data in contrast based format and run pairwise meta-analysis model results using metafor package
1 2 3 |
armbased |
A logical indicating if the data are in arm-based format (one row for each study, and one treatment in each column ) if FALSE the data are already in contrast based format. |
treat |
A list or vector with treatment information for individual treatment arms (see Details in netmeta). |
event |
A list or vector with information on number of events for individual treatment arms (see Details in netmeta pairwise function). |
n |
A list or vector with information on number of observations for individual treatment arms (see Details in netmeta pairwise function). |
mean |
A list or vector with estimated means for individual treatment arms (see Details in netmeta pairwise function). |
sd |
A list or vector with information on the standard deviation for individual treatment arms (see Details in netmenta pairwise function). |
TE |
A list or vector with estimated treatment effects for individual treatment arms (see Details in netmta pairwise function). |
seTE |
A list or vector with standard errors of estimated treatment effect for individual treatment arms (see Details in netmta pairwise function). |
time |
A list or vector with information on person time at risk for individual treatment arms (see Details in netmeta pairwise function). |
data |
Data frame in contrast-based or arm-based format |
studlab |
A vector with study labels (optional). |
incr |
A numerical value which is added to each cell frequency for studies with a zero cell count. |
allincr |
A logical indicating if incr is added to each cell frequency of all studies if at least one study has a zero cell count. If FALSE (default), incr is added only to each cell frequency of studies with a zero cell count. |
addincr |
A logical indicating if incr is added to each cell frequency of all studies irrespective of zero cell counts. |
allstudies |
A logical indicating if studies with zero or all events in two treatment arms are to be included in the meta-analysis (applies only if sm is equal to "RR" or "OR"). |
nupdate |
number of data updates |
nobs |
a vector with the number of observations for each update |
... |
optional argument to functions, you can include any parameter to run rma function from metafor pkg |
returns to .Rdata one with tde data set in contrast-based format and the second is a list with the pairwise meta analysis for each update and each pair of treatments
