Included studies had full texts available and measured multimorbidity or classic survivorship outcomes in children who received a diagnosis of cancer when younger than 20 years. Two reviewers separately screened studies for eligibility. Studies were categorized by World Bank income group and World Health Organization region. Survivorship domains were classified using an existing framework and included mental, physical, or psychosocial health, recurrences and new cancers, and health promotion. Basic quality metrics were assessed, including sample size, source, and uncertainty reporting. \u03c7\n                      <jats:sup>2<\/jats:sup>\n                      And Fisher tests were used to compare income groups and regions, linear regression for associations between publication year and income group or study domains, and the Mann-Whitney\n                      <jats:italic>U<\/jats:italic>\n                      test for sample size.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"ab-crv250005-7\">\n                    <jats:title>Findings<\/jats:title>\n                    <jats:p>A total of 1558 studies were included from 43 countries and territories, with HICs and the combined World Health Organization American and European regions disproportionately represented (1478 [95.2%] and 1436 [92.5%], respectively, of all cohort and cross-sectional studies [n\u2009=\u20091553]).
