#' Studies on the effects of transcranial direct current stimulation on
#' inhibitory control
#'
#' @description
#' Results from 62 studies, including 75 effect sizes (Hedge's g) on the effect
#' of transcranial direct current stimulation (tDCS) in inhibitory control
#' (Schroeder et al. 2020).
#'
#' @format A data frame with 75 rows and 13 variables:
#'
#' \describe{
#'   \item{\code{study_id}}{(factor) Unique id for study.}
#'   \item{\code{es_id}}{(factor) Unique id for effect size.}
#'   \item{\code{yi}}{(numeric) Effect size (Hedge's g).}
#'   \item{\code{vi}}{(numeric) Sampling variance for effect size.}
#'   \item{\code{control}}{(factor) Control condition ("active control", "no
#'   tDCS", or "sham").}
#'   \item{\code{study_design}}{(factor) Study design ("between-subjects" or

#'   stop-signal task("SST").}
#'   \item{\code{population}}{(factor) Population of study ("ADHD", "healthy" or
#'   "other patients".}
#'   \item{\code{stimulation}}{(factor) tDCS polarity ("anodal" or "cathodal").}
#'   \item{\code{intensity}}{(factor) tDCS intensity (1 mA, 1.5 mA, or 2 mA).}
#'   \item{\code{target_electrode_placement}}{(factor) Target electrode
#'   placement.}
