FORESTPLOT Subcommand (META BINARY command)

The META BINARY command calls the meta-analysis procedure for binary outcomes when the raw data are provided in the active dataset for the estimation of the effect size. The optional FORESTPLOT subcommand invokes the forest plot. The subcommand is not specified by default, which suppresses the forest plot. When the subcommand is specified, it takes the following parameters and keywords to create the forest plot. The order of the keywords determines the display order of the columns.

DISPLAY

The optional keyword specifies the estimated statistics tabulated after id and/or study.

ES: Includes the estimated effect size.
SE: Includes the standard error of the estimated effect size, which is available when /FORESTPLOT EFORM = FALSE, and is otherwise ignored.
CI: Includes the confidence interval lower and upper limits of the estimated effect size.
WEIGHT: Includes the weight of the primary studies.
PVAL: Includes the p-value of the estimated effect size for each individual study.

EFORM

The optional keyword controls the plot column and the display of ES and CI when specified by DISPLAY. The process is available when /ESTYPE = LOGOR, LOGPETO, or LOGRR, and is otherwise ignored. FALSE is the default setting, which plots the log odds ratio, Peto’s log odds ratio, or log risk ratio, and tabulates the log-transformed statistics. TRUE plots the odds ratio, Peto’s odds ratio, or risk ratio, and tabulates the exponential-form statistics.

ADDCOLS

The optional keyword specifies the additional columns to display after the columns specified by DISPLAY. The variables already specified by

/DATA
ID

and/or /DATA STUDY are not allowed. The variable order determines the column display order.

POSITION

The optional keyword controls the placement of the plot column.

RIGHT: The default setting places the plot column on the right of the other table columns.
LEFT: Places the plot column on the left of the other table columns.

SORT

The optional keyword specifies the variable upon which the sorted forest plot is based. The variable can be followed by an additional keyword specified in parentheses. ASCENDING is the default setting, which sorts the forest plot in ascending order. When DESCENDING is specified, the forest plot is sorted in descending order.

REFLINES

The optional keyword controls the reference lines that are added to the forest plot. OVERALL adds the line to denote the estimated overall effect size. NULL adds the line to denote the null effect size.

ANNOTATIONS

The optional keyword controls the display of the annotations.

HOMOGENEITY: Prints the homogeneity test statistics.
HETEROGENEITY: Prints the heterogeneity measures.
TEST: Prints the test of the overall effect size and the test of between-subgroup homogeneity in the presence of the subgroup analysis.

CROP

The optional keyword specifies the crop range. When the keyword is specified, two numeric values must be specified and satisfy value2 > value1. When /DATA ESTYPE = RD, it must also satisfy value2 ≤ 1 and value1 ≥ −1. When /FORESTPLOT /EFORM = TRUE, it must also satisfy value1 ≥ 0.
