One of the most important aspects presented by this study in Brazil was the strategies used to overcome the methodological challenges, such as: data access, data accuracy, data availability, multiple data sources, and the large follow-up period. Through multiple strategies it was possible to build a Brazilian cohort of 3,622 workers, to follow them with a 93 percent success rate and to identify in 99 percent of the cases the cause of death.

A Agência Internacional para Pesquisa sobre Câncer (IARC) propôs uma coorte histórica internacional para tentar resolver a controvérsia sobre o risco aumentado de câncer em trabalhadores das indústrias de celulose e papel. Um dos aspectos mais relevantes deste estudo no Brasil refere-se às estratégias utilizadas para superar desafios metodológicos, tais como: acesso aos dados, acurácia e disponibilidade dos dados, múltiplas fontes de dados e longo período de acompanhamento. Através de múltiplas estratégias, foi possível construir uma coorte brasileira de 3.622 trabalhadores, acompanhar 93% dos casos e identificar a causa de 99% dos óbitos. Este artigo avalia o acesso aos dados, sua acurácia e a efetividade das estratégias utilizadas para o acompanhamento da coorte.
