I have run a metanalysis using the meta package and created the following forest plot. I want to replace the 2 words Experimental and Control with Postoperative and preoperative. How can I do that?
I have used the following code to create the forest plot
forest(MD_LYSHOLM,fixed = FALSE, random = TRUE, overall= FALSE, col.random = "blue", prediction = TRUE, pooled.events = TRUE, xlab = "Mean Difference in Lysholm Scores",fs.xlab = 14,weight.study = "random", col.study = "black", col.square = "red",col.square.lines = "black", col.diamond = "black",hetstat = TRUE, overall.hetstat = FALSE, hetlab = "Heterogeneity",resid.hetstat = FALSE, print.I2 = TRUE, print.tau = TRUE)
From the documentation, I found these function arguments
label.e
Label for experimental group.
label.c
Label for control group.
Edit your code to add these arguments in your call to metacont
, which should follow over to forest
. Alternatively you can specify them directly in your call to forest using the same arguments, i.e.
forest(
MD_LYSHOLM,
fixed = FALSE,
random = TRUE,
overall = FALSE,
col.random = "blue",
prediction = TRUE,
pooled.events = TRUE,
xlab = "Mean Difference in Lysholm Scores",
fs.xlab = 14,
weight.study = "random",
col.study = "black",
col.square = "red",
col.square.lines = "black",
col.diamond = "black",
hetstat = TRUE,
overall.hetstat = FALSE,
hetlab = "Heterogeneity",
resid.hetstat = FALSE,
print.I2 = TRUE,
print.tau = TRUE,
label.c = "Pre-operative", # Added this
label.e = "Post-operative" # Added this
)
