An object of class c("metacum", "meta")
with corresponding
print
, and forest
functions. The object is a list
containing the following components:
TE, seTEEstimated treatment effect and standard error of
pooled estimate in cumulative meta-analyses.
lower, upperLower and upper confidence interval limits.
studlabStudy label describing addition of studies.
p.valueP-value for test of overall effect.
wSum of weights from fixed effect or random effects model.
I2Heterogeneity statistic I2.
RbHeterogeneity statistic Rb.
tauSquare-root of between-study variance.
df.haknDegrees of freedom for test of treatment effect for
Hartung-Knapp method (only if hakn=TRUE
).
smSummary measure.
methodMethod used for pooling.
kNumber of studies combined in meta-analysis.
pooledAs defined above.
comb.fixedA logical indicating whether analysis is based on
fixed effect model.
comb.randomA logical indicating whether analysis is based on
random effects model.
TE.fixed, seTE.fixedValue is NA
.
TE.random, seTE.randomValue is NA
.
QValue is NA
.
level.combThe level used to calculate confidence intervals for
pooled estimates.
haknA logical indicating whether the method by Hartung and
Knapp is used to adjust test statistics and
confidence intervals.
method.tauA character string indicating which method is used
to estimate the between-study variance \(\tau^2\).
tau.presetPrespecified value for the square-root of the
between-study variance \(\tau^2\).
TE.tauOverall treatment effect used to estimate the
between-study variance \(\tau^2\).
n.harmonic.meanHarmonic mean of number of observations (for
back transformation of Freeman-Tukey Double arcsine
transformation).
versionVersion of R package meta used to create object.
