R-森林图(Forest Plot)绘制方法 使用R绘制森林图(Forest Plot)的方法比较多,这里重点介绍R-forestplot包和R-ggforestplot包绘制。 「注意」:安装R-ggforestplot包之前,确保broom包已安装,否则可能会安装出错。 R-forestplot包绘制 这一部分我们直接使用提供的数据进行绘制,重点在于展示forestplot包中一些绘图参数的设置。
再次强调R语言对于大小写敏感,所以务必注意在调用R语言时,R代码中的变量名称需要与SAS中的变量名称“完全一致”。为了简化数据,只展示了一个亚组(年龄),代码如下: /*SQL set back subgroup title*/ proc SQL; create table dat1 (V1 char(8), V2 char(16), V3 char(10), V4 char(10), V5 char(22...

Choosing to call the function will require you to build the table LABEL and to control the ordering of the variables. The forest_plot help has several examples. The package also include vignettes with several step-by-step detailed examples: PK example Pediatric example PK PD example Exposure ...
Forest plots are often used in clinical trial reports to show differences in the estimated treatment effect(s) across various patient subgroups. See, for example a review. The page on Clinical Trials Safety Graphics includes a SAS code for a forest plot
The PAI time-series of forest edges (Fig.3b, Supplementary Fig.5a and5c) showed significantly distinct patterns in comparison with those observed in forests distant from edges (indicated by the significant time × edge effects interaction term; Supplementary Table1). Despite a subtle decline ...
Before regulation, average macrozoobenthos biomass in the channel did not exceed 5g/m2(Butorin and Mordukhai-Boltovskoy, 1979; Borodich and Lyakhov, 1983). In Kuibyshev reservoir, it was 12.1±2.3g/m2in 1985 and is almost double today (Table 2.2). As Cheboksary reservoir bottom became sil...
