该研究检索了Cochrane对照试验中心注册，CINAHL，Embase，LILACS数据库，MEDLINE，MEDLINEIn-Process，PsycINFO，监管机构网站，以及从一开始就发布和未发表的双盲随机对照试验的国际注册2016年1月8日。
研究包括21种抗抑郁药的安慰剂对照和头对头试验，用于成人（≥18岁和两性）的急性治疗，根据标准操作标准诊断为严重抑郁症。
主要结果是疗效（反应率）和可接受性（由于任何原因导致的治疗中断）。我们使用具有随机效应的成对和网络荟萃分析估计概要比值比（OR）。

1 程序包安装及数据加载
首先是下载和加载netmeta程序包。
##install.packages("netmeta")
library(netmeta)
eff <- read.csv("full-efficacy.csv",
header = TRUE,
stringsAsFactors = FALSE)
acc <- read.csv("full-acceptability.csv",
header = TRUE,
stringsAsFactors = FALSE)
2 模型构建（netmeta）
模型构建首先使用pairwise函数对数据处理其次鞭尸使用核心函数netmeta函数进行模型分析，可以分别选择fixed和random两类模型。
deff <- pairwise(treat = t,
n,
event = r,
data = eff,
studlab = id,
sm = "OR")
dacc <- pairwise(treat = t,
n,
event = r,
data = acc,
studlab = id,
sm = "OR")
e.netmeta <-netmeta(deff,
comb.fixed = FALSE,
comb.random = TRUE)
e.netmeta
a.netmeta <-netmeta(dacc,
comb.fixed = FALSE,
comb.random = TRUE)
a.netmeta
模型结果如下所示（仅展示e.netmeta）：

网状证据图是用来表示各种干预措施之间关系的最直观的可视化，是网状meta分析的标配，核心函数为netgraph。
-
网状meta分析的核心结果之一
-
节点：干预措施的样本量
-
线条：干预措施头对头试验，粗细代表试验数
##有效性 efficacy
netgraph(e.netmeta,
start ="circle",
cex = 1,
col = "black",
plastic = FALSE,
points = TRUE,
col.points = "steelblue",
cex.points =15*sqrt(n.trts/max(n.trts)),
thickness = "number.of.studies",
lwd.max = 12,
lwd.min = 1,
multiarm = F)
netgraph(a.netmeta,

cex = 0.7,

cex.points =15*sqrt(n.trts/max(n.trts)),
thickness = "number.of.studies",
lwd.max = 12,
lwd.min = 1,
multiarm = FALSE)
4 森林图（forest plot）
森林图是meta分析的标配，在网状meta中也是一样的，如图所示，森林图给出了各干预措施比较的效应量及95%可信区间，当然，也给出了预测区间。
主要使用forest函数实现。
forest(e.netmeta,
ref = "placebo",
pooled = "random",
digits = 2,
col.square = "steelblue",
smlab = "Random effects model",
label.left = "Favors citalopram",
label.right = "Favors the other",
leftlabs = "Efficacy",
drop = TRUE,
sortvar = -TE)
forest(a.netmeta,
ref = "placebo",
pooled = "random",
digits = 2,
col.square = "darkred",
xlim = c(2, 0.5),
smlab = "Random effects model",
label.left = "Favors the other",
label.right = "Favors citalopram",
leftlabs = "Acceptability",
drop = T,
sortvar = TE)
6 两两比较赛联表（league）
赛联表为网状meta两两比较结果，使用netleague函数实现。
league <- netleague(e.netmeta,
a.netmeta,
backtransf = TRUE,
direct = FALSE,
fixed = FALSE,
digits =2,
bracket = "(",
separator = " to ")

6 节点分割法（netsplit）
不一致性是指网状meta分析中直接证据和间接证据存在差异，这会影响网状meta分析的真实性，因此需要在进行网状meta分析时进行检测，并分析不一致性的产生原因。对于三个治疗措施形成的闭合环，就可以直接比较直接证据和间接证据之间的不一致性。对于四个研究形成的闭合环，可以分割成两个闭合的三角形环，进而分析直接证据和间接证据之间的不一致性。
常用的不一致检验方法为节点分割法，使用netsplit函数实现：

7 热图（netheat plot）
-
一种判断不一致性的方法，图中的灰色方块在row方向中越大表示研究越重要，颜色越红代表研究一致性越大。
netheat(e.netmeta,
nchar.trts = 4,
random = TRUE)
8 排序图（SURCA plot）
对干预措施的优劣进行排序是网状meta分析的一大特色，也是一个主要的优势。目前排序的方法比较多，最常用的有SUCRA法和P得分法，其中，SUCRA法是最为常用的方法，该值越大为最佳干预措施的可能性越大。
netrank(e.netmeta, small.values = "bad") #可做条形图

发表偏倚检测实际上是和传统meta分析一致的，主要靠漏斗图来实现。解读方法看是否对称，是一个主观判断。
colors <- c(
agom = "thistle", amit = "lightgreen",
bupr = "coral3", cita = "cadetblue4",
clom = "orange3",esci = "pink",
fluv = "dodgerblue4", miln = "goldenrod4",
mirt = "yellow3", nefa = "darkgrey",
paro = "gray9", rebo = "lightblue3",
sert = "lightslateblue", traz = "red4",
venl= "mediumvioletred")
trts_ef <- substr(e.netmeta$trts, 0, 4)
trts_ac <- substr(a.netmeta$trts, 0, 4)
comparison_ef<- trts_ef[trts_ef != "fluo"]
comparison_ac <- trts_ac[trts_ac != "fluo"]
ord_ef<- c(comparison_ef, "fluo")
ord_ac <- c(comparison_ac, "fluo")
然后使用funnel函数进行漏斗图进行绘制:
funnel(netmeta_ef,
order = ord_ef,
pch = rep(19),
col = colors,
legend = FALSE,
linreg = TRUE,
text.linreg = "(Egger's test)",
pos.tests = "topright")
legend("topleft",
legend = comparison_ef,
pch = rep(19),
col = colors,
cex = 0.75)
funnel(
netmeta_ac,
order = ord_ac,
pch = rep(19),
col = colors,
legend = FALSE,
linreg = TRUE,
text.linreg = "(Egger's test)",
pos.tests = "topright")
legend("topleft",
legend = comparison_ac,
pch = rep(19),
col = colors,
cex = 0.75)
