The information available for each trial, along with the name of the first author ( author) and the year of publication ( year), is: 6 It consists of 17 trials comparing haloperidol and placebo, the outcome of interest is clinical improvement and the chosen measure of association is the risk ratio (RR), with an RR larger than 1 meaning that haloperidol is better than placebo. 10 It has already been used to assess the impact of missing data on clinical outcomes 11 and as working example in Chaimani et al. The dataset used in this paper comes from a Cochrane review evaluating the effect of haloperidol in the treatment of symptoms of schizophrenia. In this publication, we want to print all results with two significant digits: ta ( digits = 2 ). Among other things, the overview mentions that we can use the ta function to define default settings for the current R session. The library function can be used to make the R packages available in the current session:Ī brief and very helpful overview of R package meta is provided by the R command help(meta).

RStudio users can also install packages via the menu: Tools ->Install Packages… Third, function arguments are separated by commas that is visible in the call of function c(). Second, the argument of an R function can be another R function here we use the function c() to combine the names of R packages. packages (without brackets) would show the definition of the function. First, we use brackets in order to execute an R function, here instal l. Using this first R command, we would like to mention three general properties of R commands. In the following, we present R commands to:Ĭonduct a meta-analysis when the outcome of interest is binary.Īssess the impact of missing outcome data.Īssess and account for small-study effects.īefore conducting a meta-analysis, the R packages meta and metasens need to be installed, 9 which include all functions to perform the analyses and to create the figures presented in this publication. In this publication, we replicate these analyses in R using the packages meta 7 and metasens.

The freely available statistical software environment R 4 ( ) and the commercial software Stata 5 provide the largest collection of statistical methods for meta-analysis. 2 In general, the use of meta-analysis has been increasing over the last three decades with mental health as a major research topic, for example, in Cochrane reviews. 1 Systematic reviews and meta-analysis as statistical method to combine results are cornerstones to yield an unbiased assessment of the available evidence. Evidence synthesis is the basis for decision making in a large range of applications including the fields of medicine, psychology and economics.
