Abbreviations: CI, confidence interval; HR, hazard ratio; LMM, lentigo maligna melanoma; NM, nodular melanoma; NOS, not otherwise specified; SSM, superficial spreading melanoma.

^aAll analyses were stratified by sex and 5-year birth cohorts.

^bThe reference child has a height z-score of 0, a ‘taller’ child has a z-score of 0.5, and a ‘persistently taller’ child has a z-score of 0.5 at both age 7 years and 13 years.
