Как отобразить вес в анализе подгрупп в Metafor / R?

Question

Я подготовил Лесной участок в приложении.

Я применил showweights = TRUE, что дает мне вес каждого исследования для всей оценки.

Тем не менее, я провел анализ подгрупп на основе некоторых основных характеристик исследования. Анализ каждой подгруппы дает оценку подгруппы. Можно ли показать весовые коэффициенты для оценки подгруппы?

My data
q <- structure(list(study = structure(c(1L, 4L, 5L, 6L, 2L, 3L), .Label = c("Ho et al.", "Lee et al.", "Li et al. ", "Plontke et al.", "Wu et al.", "Xenellis et al."), class = "factor"), ai = c(11L, 6L, 24L, 9L, 10L, 9L), bi = c(4L, 5L, 3L, 10L, 11L, 15L), ci = c(7L, 5L, 6L, 0L, 4L, 0L), di = c(7L, 5L, 22L, 18L, 21L, 21L), year = c(2004L, 2009L, 2011L, 2006L, 2011L, 2010L), citation = structure(c(6L, 4L, 2L, 5L, 1L, 3L), .Label = c("[23]", "[24]", "[25]", "[26]", "[27]", "[28]"), class = "factor"), mod = c(1L, 1L, 0L, 0L, 1L, 0L), bias = c(1L, 0L, 0L, 1L, 1L, 1L), n1 = c(15L, 11L, 27L, 19L, 21L, 24L), n2 = c(14L, 10L, 28L, 18L, 25L, 21L), follow = c(0L, 0L, 0L, 1L, 1L, 1L)), .Names = c("study", "ai", "bi", "ci", "di", "year", "citation", "mod", "bias", "n1", "n2","follow"), class = "data.frame", row.names = c(NA, -6L)) 

Я привык к следующему сценарию:

library(metafor)
q <- escalc(measure="OR", ai=ai, bi=bi, ci=ci, di=di, data=q)
q1 <- rma(yi, vi, data=q, slab=paste(study, year, citation, sep=", "), method = "FE")

       ilab.xpos=c(-11,-9.5,-8.0,-6,-4.5,-3), cex=1, ylim=c(-1, 18), font=1, digits=2, col="darkgrey",
       order=order(q$mod),
       rows=c(3.5:5.5,11.5:13.5),
       xlab="Odds ratio ", mlab="")
