Additional arguments for |
A funnel plot is drawn in the active graphics window. In addition
this function adds the adjusted effect estimate as well as a
nonlinear regression line (also called adjusted regression line) if
argument line
is TRUE
. The adjusted regression line
is representing the dependence of the treatment effect estimate on
the standard error across studies. The adjusted regression line is
only plotted in addition to the adjusted treatment effect if
argument method.adjust="beta0"
(default) has been used in
the limitmeta
function.
If argument shrunken
is TRUE
the shrunken effect
estimates are also plotted. Lines are connecting original and
shrunken effect estimates.
Internally, R function funnel.meta
is called to
create a funnel plot. For more information see help page of the
funnel
function.
