R语言 m26 - metacontPost_N_TreatmentPost_Mean_Treatment Post_SD_TreatmentPost_N_Control Post_Mean_ControlPost_SD_Control data = df_readingaccuracysm=SMD

可以在metacont函数中通过设置studlab参数来实现，具体操作如下：

1. 在metacont函数中添加studlab参数，将其设置为作者+年代的格式，例如：studlab=paste(df_readingaccuracy$Author,df_readingaccuracy$Year)

2. 在forest函数中添加labpar参数，将其设置为list(cex=0.8),以调整标签大小，避免过大。

修改后的代码如下：

m26 <- metacont(Post_N_Treatment,Post_Mean_Treatment, Post_SD_Treatment,Post_N_Control, Post_Mean_Control,Post_SD_Control, data = df_readingaccuracy,sm="SMD", comb.fixed=FALSE,comb.random=TRUE, studlab=paste(df_readingaccuracy$Author,df_readingaccuracy$Year)) m26 forest(m26,xlim = c(-2, 2),labpar=list(cex=0.8)
