In nshi-stat/pimeta: Prediction Intervals for Random-Effects Meta-Analysis

#' Set-shifting data
#'
#' Higgins et al. (2009) re-analyzed data (Roberts et al., 2007)
#' that included 14 studies evaluating the set-shifting ability
#' in people with eating disorders by using a prediction interval.
#' Standardized mean differences in the time taken to complete
#' Trail Making Test between subjects with eating disorders and
#' healthy controls were collected.
#' Positive estimates indicate impairment in set shifting ability
#' in people with eating disorders.

#' Pain data
#'
#' The pain data (Riley et al., 2011; Hauser et al., 2009) included
#' 22 studies comparing the treatment effect of antidepressants on
#' reducing pain in patients with fibromyalgia syndrome.
#' The treatment effects were summarized using standardized mean
#' differences on a visual analog scale for pain between the
#' antidepressant group and control group.
#' Negative estimates indicate the reduction of pain in the
#' antidepressant group.

#' Hypertension data
#'
#' The hypertension data (Wang et al., 2005) included
#' 7 studies comparing the treatment effect of
#' anti-hypertensive treatment versus control on reducing
#' diastolic blood pressure (DBP) in patients with hypertension.
#' Negative estimates indicate the reduction of DBP in the
#' anti-hypertensive treatment group.
