[R-meta] Query on forestplot

[Emanuel Schembri]

Hi,

Thank you for the Meta package, which I use a lot.

I am trying to replicate the meta-analysis of single proportions
(Figure 3), which can be found in the paper below:

https://bmcmusculoskeletdisord.biomedcentral.com/articles/10.1186/s12891-021-04322-5



Below are my R version and operating system:

R version 4.3.1 (2023-06-16 ucrt)

Platform: x86_64-w64-mingw32/x64 (64-bit)

Running under: Windows 10 x64 (build 19045)



Below is the data  and code:

> dput(E1)

structure(list(author = c("Hemery, 2011", "Joshy, 2007", "Mayr, 2000",

"Nolte, 2001", "Romano, 2006", "Rutten, 2007"), event = c(4,

2, 13, 2, 39, 3), n = c(6, 2, 13, 2, 49, 6)), class = c("tbl_df",

"tbl", "data.frame"), row.names = c(NA, -6L))





meta_analysis <- metaprop(

  event = event,

  n = n,

  studlab = author,

  data = data,

  sm = "PLOGIT",

  method = "GLMM",

  fixed = FALSE,

  random = TRUE,

  method.tau = "ML"

)



forest(meta_analysis)





Questions:

1.      How can I add the total number of events in the forest plot? I
also had this issue in a separate meta-analysis and forest plot when
using 1). metabin() and 2). metabin() with subgroups.

2.      How can I remove the df = 5 or else make the Heterogeneity
statistics not overlap with the 0.2 in the forest plot?



Thank you

Emanuel
