catmap.forest: catmap: Forest Plot

In catmap: Case-Control and TDT Meta-Analysis Package

Description

The catmap.forest creates forest plots of the individual study Odds Ratios (OR) and Confidence Intervals (CI). It then summarizes the data using a fixed-effects or random-effects pooled OR and CI.

Usage

catmap.forest(catmapobject, fe.forest = FALSE, re.forest = FALSE)

Arguments

catmapobject	A catmap object created by catmap.
fe.forest	A boolean. Toggles whether the forest plot should get saved to the current working directory.
re.forest	A boolean. Toggles whether the forest plot should get saved to the current working directory.

Author(s)

Algorithm designed and implemented by Kristin K. Nicodemus. Code modified and updated by Thom Quinn.
