  1. Objectivity of article assessment was determined using the Kappa coefficient of agreement via independent assessments of a subset of articles [31].
  2. *17 articles could not be assessed and were excluded at this stage due to being written in a language other than English, because of unanswered data requests, or because the original source material could not be located or no longer existed. Data were either unavailable or not extractable for a further 13 articles.
