FUNNELPLOT Subcommand (META ES BINARY command)
The META ES BINARY command calls the meta-analysis procedure for binary outcomes when the pre-calculated effect size data are provided in the active data set. The optional FUNNELPLOT subcommand invokes the funnel plot. The subcommand is not specified by default, which suppresses the funnel plot. When the subcommand is specified, it takes the following parameters and keywords to create the funnel plot.
- IMPUTE
- The optional keyword controls whether the observed and imputed studies are
included in the funnel plot when /TRIMFILL is specified. The keyword is ignored
in the absence of /TRIMFILL. FALSE is the default setting,
which excludes the observed and imputed studies. TRUE includes the imputed
studies. When
TRUE(REFLINE)
is specified, it adds the vertical reference line to denote the estimated overall effect size, taking into account both observed and imputed studies. - YAXIS
- The optional keyword controls the y-axis.
- SE
- The default setting that plots standard deviation.
- INVSE
- Plots inverse standard deviation.
- VAR
- Plots variance.
- INVVAR
- Plots inverse variance.
- LABEL
- The optional keyword specifies the variable upon which the labeled funnel plot is based. The variable can be followed by an additional keyword specified in parentheses. AUTO is the default setting, which automatically places the labels in the “optimal” place. UPPER, BOTTOM, RIGHT, and LEFT places the labels on the upper, bottom, right, and left, respectively.
- YRANGE
- The optional keyword specifies the y-axis plot range. When the keyword is
specified, two numeric values must be specified and satisfy
value2 > value1 ≥ 0
. - XRANGE
- The optional keyword specifies the x-axis plot range. When the keyword is
specified, two numeric values must be specified and satisfy
value2 > value1
