Older children often exhibit higher disease activity, whereas early-onset cSLE is associated with worse outcomes. However, most existing studies are retrospective and based on single-nation cohorts, yiedling inconsistent findings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To investigate age-related variations in cSLE subgroups, namely prepubertal, peripubertal, and adolescent-onset cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This systematic review, registered in PROSPERO and conducted in accordance with PRISMA guidelines, searched PubMed, the Cochrane Library, and Web of Science for English-language studies pubslished between January 2000\u2013 February 2025. Eligible studies examined age-related variations in cSLE diagnosed before 18\u00a0years of age. Data were categorized into prepubertal, peri-pubertal, and adolescent-onset groups. Exclusion criteria included case reports, comments, editorials, viewpoint articles, conference abstracts, and incomplete studies. Four reviewers independently screened the articles, with discrepancies resolved by a fifth reviewer. Study quality was assessed using the NHLBI criteria.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of 16,313 studies screened, 13 met the inclusion criteria, comprising a total of 3920 cSLE cases. Among these, 464 (11.8%) were prepubertal, 1943 (49.6%) peripubertal, and 1513 (38.6%) adolescent-onset. The mean age at diagnosis was 5.8 \u00b1 2.3, 9.4 \u00b1 2.5, and 13.9 \u00b1 1.1\u00a0years, respectively. The female-to-male ratio was highest in the adolescent-onset group (\n                      <jats:italic>p<\/jats:italic>\n                      = .002). Clinical manifestations showed no significant age-related differences; however, musculoskeletal involvement increased with age, while neuropsychiatric symptoms and fever decreased. Lymphopenia was more frequent in the adolescent-onset group (60% vs 25.6%,\n                      <jats:italic>p<\/jats:italic>\n                      = .016). Although disease activity and damage did not differ significantly across age groups, mortality was signficantly higher in the prepubertal group (16.5%) compared to the adolescent-onset group (2.9%) (\n                      <jats:italic>p<\/jats:italic>\n                      = .014).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This review underscores both similarities and differences in cSLE across age groups.
