rob.summary.Rd
This function generates summary plots for study quality assessments using the Cochrance Risk of Bias Tool. Summary plots follow the style of RevMan Risk of Bias (RoB) summary charts.
rob.summary(data, name.high="High", name.unclear="Unclear", name.low="Low", studies, name.missing, table = FALSE)
data | A |
---|---|
name.high | Character specifying how the "high risk of bias" category was coded in |
name.unclear | Character specifying how the "unclear risk of bias" category was coded in |
name.low | Character specifying how the "low risk of bias" category was coded in |
studies | A vector of the same length as the number of rows in |
name.missing | Character specifying how missing information was coded in |
table | Should an additional RevMan style risk of bias table be produced? If set to |
The function automatically removes separators like "-" or "." from column names/risk of bias criteria. To produce
a "clean" plot, you may therefore separate words in the column names of the data
data frame using these
symbols (e.g. "Allocation_Concealment"
to return "Allocation Concealment").
