    forestplot(ci; sourcelabel = "Source:", metriclabel = "OR", cilabel = "CI95%", 
    source = nothing, metric = nothing, printci = false,
    summary = nothing, logscale = true, kwargs...)

By default plot is logscaled.

• ci - vector (iterable) of confidence intervals bounds;
• source - vector of study names (String);
• metric - vector of metric estimates;
• printci - print confidence interval;
• summary - print summary object (Dict);
• logscale - if true CI will be transformed (exp function used);
• cimsz - CI marker size, -1 or any value < 0 - auto;
• cimszwts - CI marker size weights (if nothing - metric will be used);
• size - size of plot;
• metriclabel = "OR" - label for metrics values;
• cilabel = "CI95%"- label for intervals values
• ps = 10 - font size in points;

Example

using ForestPlot

forestplot([[0.2,1.2], [0.8,1.4], [0.6, 0.8], [1.2, 1.6]], 
sourcelabel = "Study:", metriclabel = "Estimate",
metric = [1.0, 1.2, 0.7, 1.3], 
source = ["12345678901234567890", "B", "C", "D"])

Summary object

Summary is a Dict() with keywords:

• :ci
• :est
• :vline (true/false or vlues for vertical lines)
• :markershape
• :markersize

Example 1

forestplot([[0.2,1.2], [0.8,1.4], [0.6, 0.8], [1.2, 1.6]], 
metric = [1.0, 1.2, 0.7, 1.3], source = ["A", "B", "C", "D"],
summary = Dict(:ci =>[0.8, 1.1], :est => 0.95, :markershape => :rtriangle), logscale = false)

Example 2

ForestPlot.forestplot([[0.2,1.2], [0.8,1.4], [0.6, 0.8], [1.2, 1.6], [0.3, 0.7], [1.2, 1.5], [1.2, 1.3]], 
    metric = [1.0, 1.2, 0.7, 1.3, 0.5, 1.2, 1.3], source = ["A", "B", "C", "D", "E", "F", "G"],
    sourcelabel = "Study:", metriclabel = "Estimate", 
    summary= Dict(:ci => [0.75,1.15], :est => 0.9), 
    logscale = true, printci = true, title = ["" "Title"], size = (800, 400))

Example 3 (no source)

ForestPlot.forestplot([[0.2,1.2], [0.8,1.4], [0.6, 0.8], [1.2, 1.6], [0.3, 0.7], [1.2, 1.5], [1.2, 1.3]], 
    metric = [1.0, 1.2, 0.7, 1.3, 0.5, 1.2, 1.3],
    sourcelabel = "Study:", metriclabel = "Estimate", 
    summary= Dict(:ci => [0.75,1.15], :est => 0.9), 
    logscale = true,title = "Title")
