#' Differential Effects of Cognitive Behavioral Therapy Delivery Formats in Depressive Patients dataset
#'
#' This data set contains simulated effect sizes of randomized controlled trials evaluating the (relative) effectiveness of
#' cognitive behavioral therapy for depression, using different delivery formats.

#' @details This simulated data set is based on pooled results of a network
#' meta-analysis examining the effects of different cognitive behavioral therapy
#' (CBT) delivery formats in adults with depression (Cuijpers et al., 2019). Using
#' network meta-analysis techniques on this data set will yield roughly similar,
#' although not identical results to the ones reported in the original study.
#'
#' For the simulation, pooled effects within designs as reported in Cuijpers et al. along with the estimated
#' between-study heterogeneity variance were assumed as true population parameters.
#' Based on these "true" population parameters, simulations
#' were generated assuming a (random-effects) bayesian hierarchical model, using a
#' non-central chi-squared distribution for the simulation of study-specific sampling errors.
#' The number of effect size draws was chosen to (approximately)
#' mimic the number of comparisons in the original analysis.
#'
#' This is an alternative version of the data set, adapted for out-of-the-box usage in \code{gemtc}.
