rob_summary: Produce summary weighted barplots of risk-of-bias...

In robvis: Visualize the Results of Risk-of-Bias (ROB) Assessments

Description

A function to convert standard risk-of-bias output to tidy data and plot a summary barplot.

Usage

rob_summary(data, tool, overall = FALSE, weighted = TRUE,
  colour = "cochrane", quiet = FALSE)

Arguments

data	A dataframe containing summary (domain) level risk-of-bias assessments, with the first column containing the study details, the second column containing the first domain of your assessments, and the final column containing a weight to assign to each study. The function assumes that the data includes a column for overall risk-of-bias. For example, a ROB2.0 dataset would have 8 columns (1 for study details, 5 for domain level judgments, 1 for overall judgements, and 1 for weights, in that order).
tool	The risk of bias assessment tool used. RoB2.0 (tool='ROB2'), ROBINS-I (tool='ROBINS-I'), and QUADAS-2 (tool='QUADAS-2') are currently supported.
overall	An option to include a bar for overall risk-of-bias in the figure. Default is FALSE.
weighted	An option to specify whether weights should be used in the barplot. Default is TRUE, in line with current Cochrane Collaboration guidance.
colour	An argument to specify the colour scheme for the plot. Default is 'cochrane' which used the ubiquitous Cochrane colours, while a preset option for a colour-blind friendly palette is also available (colour = 'colourblind').
quiet	An option to quietly produce the plot without displaying it.

Value

Risk of bias assessment barplot figure.

Examples

data <- data.frame(stringsAsFactors=FALSE,
                   Study = c("Study 1", "Study 2"),
                   D1 = c("Low", "Some concerns"),
                   D2 = c("Low", "Low"),
                   D3 = c("Low", "Low"),
                   D4 = c("Low", "Low"),
                   D5 = c("Low", "Low"),
                   Overall = c("Low", "Low"),
                   Weight = c(33.33333333, 33.33333333)
                   )
