Hi, I have read this: https://mcguinlu.github.io/robvis/articles/metafor.html There is a step in it like: ``` # Create some example data for ROB2 using rob_dummy(), and add it to the BCG# data.# We don't need a "Study" column for this example, so we set `study = FALSE`dat_rob <- rob_dummy <https://mcguinlu.github.io/robvis/reference/rob_dummy.html>(13, "ROB2", study = FALSE)dat_analysis <- cbind <https://rdrr.io/r/base/cbind.html>(dat_bcg, dat_rob) ``` Why dat_rob was created and attached to dat_bcg ? What is this for ? Is it only an example to show coloured visualisation ? Or does it thoroughly calculating ROB for bcg.data ? And here: https://bookdown.org/MathiasHarrer/Doing_Meta_Analysis_in_R/risk-of-bias-plots.html they described an excel table with some data to be created before importing it to R. Anybody knows what is this about ? best, Andrzej

Dear Andrzej, Please post in plain text (note how the code in your post below is quite mangled up). I am not sure if I quite understand your questions, but 'dat_rob' was created to illustrate how to add risk of bias assessments to a forest plot. It was created with rob_dummy(), which just simulates some RoB values for a given dataset for illustration purposes: https://mcguinlu.github.io/robvis/reference/rob_dummy.html As for that book chapter: The spreadsheet contains the RoB assessments for the dataset used in their example. Not sure what else to say about this. Best, Wolfgang

Dear Wolfgang, thank you for clarification. I misunderstood for what Robvis was created. I thought it was there to assess and help with publication bias and not to add a few coloured circles to the forest plot.I found this: DOI: 10.1111/2041-210X.13724 and will study it. best, Andrzej wt., 7 lis 2023 o 10:50 Viechtbauer, Wolfgang (NP) < wolfgang.viechtbauer at maastrichtuniversity.nl> napisa?(a):
