See Methods for full definition of asbestos ban and mesothelioma identification.
*Six ‘early-banned’ countries that banned asbestos in or before 1990, that is, Austria, Denmark, Iceland, Norway, Sweden and Switzerland, are precluded from this analysis and are analysed separately in table 4. See Methods for full explanation.
†) Period before the year of ban in asbestos-banned countries and period before 2019 in not-banned countries.
‡) Variance inflation factor (VIF) was used to assess collinearity between explanatory variable; VIF were 1.026 for mesothelioma identification and 1.025 for mesothelioma MR during 1–5 years before year of ban or 2019.
