Description Usage Arguments Value Note References Examples
Creates a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) flow diagram depicting the 'flow' of study inclusions and exclusions during various systematic review phases. It is meant to describe the number of studies identified, included, excluded, reasons for inclusion/exclusions, and final number of studies used in the meta-analysis. NOTE: currently only supports two start phases, and final phase must not have an exclude branch.

aPhaseVector |
A vector of ordered labels (strings) for each phase of the PRISMA diagram. Labels designating the beginning of the diagram are commented with "START_PHASE: " and those designating exclusion phases "EXCLUDE_PHASE: ". These comments will be removed from the diagram. |
colWidth |
An optional value (integer) designating the width of the text box of each phase. |
excludeDistance |
An optional value designating the the distance of exclude phase box from the main flow diagram. Larger values (> 0.8) increase this distance. |
design |
Designates the colorscheme and design of the the flow diagram.
The default is |
hide |
When FALSE, the PRISMA flow diagram is not plotted. |

Using canned or custom PRISMA design layouts
There are
several color schemes and design layouts (e.g. curved or flat) available.
These designs include: cinnamonMint
, sunSplash
, pomegranate
,
vintage
, grey
, and greyMono
. Custom schemes can also
be developed by modifying each aspect of the design. These are:
color of start phases (default: white)
color of the main phases (default: white)
color of the exclusion phases (default: white)
color of the final phase (default: white)
the size of the font (default: 12)
the font color (default: black)
either plain, bold, italic, or bold.italic (default: plain)
arrows curved when FALSE (default); arrows square when TRUE
boxes curved when FALSE (default); Boxes square when TRUE
For example, changing the defaults to have red rather than white exclusion
phases, and square boxes, would be: design = c(E = "red", flatBox = TRUE)
