#' Prevention of Eating Disorders at Universities dataset
#'
#' This is a dataset containing effect size data of a meta-analysis synthesizing
#' randomized controlled trials comparing the preventive effect of psychobehavioral interventions
#' delivered at universities on incidence rates of subthreshold and full-symptom eating disorders.
#' Effect size data is provided as the number of cases and the person time at risk calculated for
#' the intervention and control group.

#' @format A \code{data.frame} with 5 columns.

#' @details This data set was used in a meta-analysis examining the effect of preventive eating disorder interventions
#' at universities (Harrer et al., 2020). The data refers to the analysis in which the treatment arms of trials
#' with more than one intervention group were combined so that each study is the meta-analysis is statistically independent;
#' resulting in slightly different results then the ones reported in the abstract of the article. Person time at risk values
#' were rounded and therefore differ slightly from the ones reported in the study.
