Cumulative Forest Plot

The Cumulative Forest Plot tab provides settings for controlling cumulative forest plot charts that display in the output for meta-analysis with continuous and binary outcomes when raw data and pre-calculated effect size data are provided in the active data set.

Cumulative forest plot
The optional setting enables and disables forest plot output. The setting is disabled by default.
Display Columns
The optional settings specify the estimated statistics that are tabulated.
Cumulative effect size
Includes the cumulative overall effect size.
Standard Error
Includes the standard error of the cumulative overall effect size.
Confidence interval limits
Includes the confidence interval lower and upper limits of the cumulative overall effect size.
P-value
Includes the p-value of the cumulative overall effect size for each individual study.
Display exponentiated form
Note: This setting applies only to meta-analysis with binary outcomes.
Controls the plot column and the display of effect size and confidence interval. When the setting is selected, it plots the odds ratio, Peto’s odds ratio, or risk ratio, and tabulates the exponential-form statistics. When the setting is not enabled, it plots the log odds ratio, Peto’s log odds ratio, or log risk ratio, and tabulates the log-transformed statistics.
Variables
Lists the available dataset variables.
Additional Columns
Optionally, select variables to display as additional columns. The variable order determines the column display order.
Position of plot column
Controls the placement of the plot column.
Right
The default setting places the plot column to the right of the other table columns.
Left
Places the plot column to the left of the other table columns.
Crop Range
Specifies the crop range. When the setting is selected, two numeric values must be specified and satisfy Upper bound > Lower bound.
For meta-analysis with binary outcomes, when the Effect Size setting is set to Risk Difference, it must also satisfy Upper bound ≤ 1 and Lower bound ≥ −1. When the Display exponentiated form setting is selected, it must also satisfy Lower bound ≥ 0.

Defining cumulative forest plot settings

  1. From the menus choose:

    Analyze > Meta Analysis > Continuous Outcomes or Binary Outcomes > Raw Data... or Pre-Calculated Effect Size...

  2. In the Meta-Analysis dialog, click Plot and then click the Cumulative Forest Plot tab.
  3. Select and define the appropriate cumulative forest plot settings.
  4. Click Continue.
