Objectivity of article assessment was determined using the Kappa coefficient of agreement via independent assessments of a subset of articles [29]. Articles were assessed by three reviewers (RW, JE and LEN).
*79 articles could not be assessed and were excluded at this stage due to being written in a language other than English or required additional information from the authors before inclusion due to insufficient/unclear reporting.
