I currently work on network meta-analysis project. My study aim to compare the efficacy of some drugs to reduce relieve pain. Small value are desirable using SMD. From other study, I saw that the netleague result should be (-) result to show the magnitude of pain "reduction". However, after several trial and error, my netleauge table showing (+) result with the inverted CI value (they should (-) but the result (+), or vice versa).
Those are my syntax in r programming.
\#2 pairwise ssPainDurWF \<- pairwise(treat = t, mean = y, sd = sd, n = n, studlab = study, sm = "SMD", data = ssPainDur) ssPainDurWF ssPainDurNMA \<- netmeta(TE = TE, seTE = seTE, treat1 = treat1, treat2 = treat2, studlab = studlab, sm = "SMD", data = ssPainDurWF, small.values = "desirable", fixed = FALSE, random = TRUE, sep.trts = "vs", reference.group = "Control", details.chkmultiarm = TRUE) ssPainDurNMA summary(ssPainDurNMA) decomp.design(ssPainDurNMA) ssPainDurNMA$trts result.matrix \<- ssPainDurNMA$TE.random result.matrix \<- round(result.matrix, 2) result.matrix\[lower.tri(result.matrix, diag = FALSE)\] \<- NA netleague \<- netleague(ssPainDurNMA, bracket = "(", # use round brackets digits=2) # round to two digits write.csv(netleague$random, file = "/Users/defiefendi/downloads/bismillah.csv")
I also try another syntax, but the result remain the same.
I have tried to follow number of examples from similar study. Also find books which provide syntax in R programming. I have follow their code and steps. The result remain incorrect.
I hope someone can help me to resolve the issue.
Please kindly provide help.
