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.
