我可以在 metafor 的 Forest Plot 中更改从 ilab=cbind 加载的文本的颜色吗？

Question

请在下面找到我的数据 q。

我制作了这个森林图，我希望圈出的文字是红色而不是黑色。这可以做到吗？

我的脚本

q <- escalc(measure="IRR", x1i=x1i, t1i=t1i, x2i=x2i, t2i=t2i, data=q)
q1 <- rma(yi, vi, data=q, slab=paste(study, sep=", "), method = "REML")

## Forest
forest(q1, xlim=c(-27,8), atransf=exp, showweights = FALSE, psize = 1.6, refline=log(1),
       cex=0.5, ylim=c(0.1, 17), font=1, col="white", border="white", order=order(q$order),
       ilab=cbind(q$x1i, q$t1i, q$ir1, q$x2i, q$t2i,q$ir2),
       ilab.xpos=c(-19.3,-17,-15,-12.3,-10,-8),
       rows=c(2:7,11:13),xlab="Rate ratios", mlab="")

# Headlines
text(c(-19,-16.8,-15,-12,-9.8,-8)   ,15.7,font=1, cex=0.5, c("Events\n per total\n", "Person-\nyrs\n", "IR\n", "Events\n per total\n", "Person-\nyrs\n","IR\n"))
text(c(-18.75,-18.75,-18.65)   ,c(13,12,11),font=1, cex=0.54, c("/ 32", "/ 32", " / 23"))
text(c(-18.75,-18.75,-18.75)   ,c(7,6,5),font=1, cex=0.54, c("/ 37", "/ 37", "/ 37"))
text(c(-18.65,-18.65,-18.65)   ,c(4,3,2),font=1, cex=0.54, c(" / 29", " / 29", " / 19"))

text(c(-11.65,-11.65,-11.65)   ,c(13,12,11),font=1, cex=0.54, c("  /23", " /16", " /16"))
text(c(-11.65,-11.65,-11.75)   ,c(7,6,5),font=1, cex=0.54, c(" /29", "/19", "  /25"))
text(c(-11.65,-11.75,-11.75)   ,c(4,3,2),font=1, cex=0.54, c("/19", " / 25", " / 25"))


text(8                       ,15.7,font=1, "Rate ratio [95% CI]", pos=2, cex=0.5)
text(-27                     ,c(14,8),font=2, c("Progression rates","Mortality rates"), pos=4, cex=0.5)
text(-27                     ,c(1,10),font=1, c("\nCohort: 110 patients included","\nCohort: 76 patients included"), pos=4, cex=0.45)

我的数据q

6L, 9L), .Label = c("WHO-I versus Unknown ", "WHO-I versus WHO-II",

无法更改通过 ilab 添加的内容的颜色，但您始终可以使用 text() 自己添加文本（例如，在现有文本之上）。这样做就可以了：

text(-15, rev(c(2:7,11:13)), q$ir1, col="red", font=1, cex=0.5)
text( -8, rev(c(2:7,11:13)), q$ir2, col="red", font=1, cex=0.5)

我可以在 metafor 的 Forest Plot 中更改从 ilab=cbind 加载的文本的颜色吗？

Can I change the color of the text loaded from ilab=cbind in Forest Plot in metafor?
