The authors wish to make the following amendments to their paper published in International Journal of Environmental Research and Public Health [1]. These amendments only apply to the data from Brazil:
Page 11692, the abstract, line 15, the data collection for “Awareness of e-cigarettes” in Brazil should be 37%, and the data for “Trial of Electronic Cigarettes” in Brazil should be 8%. The correct sentence should be “There was considerable cross-country variation by year of data collection and for awareness of e-cigarettes (Netherlands (2013: 88%), Republic of Korea (2010: 79%), United States (2010: 73%), Australia (2013: 66%), Malaysia (2011: 62%), United Kingdom (2010: 54%), Canada (2010: 40%), Brazil (2013: 37%), Mexico (2012: 34%), and China (2009: 31%)), in self-reports of ever having tried e-cigarettes (Australia, (20%), Malaysia (19%), Netherlands (18%), United States (15%), Republic of Korea (11%), United Kingdom (10%), Brazil (8%), Mexico (4%), Canada (4%), and China (2%)), and in current use (Malaysia (14%), Republic of Korea (7%), Australia (7%), United States (6%), United Kingdom (4%), Netherlands (3%), Canada (1%), and China (0.05%))”.
Page 11696, Table 1, the data for Brazil are corrected. There are no changes in the data of any of the other countries. The corrected Table 1 is as follows:

Notes: Between-country comparisons cannot be made due to differences in survey timing and sequence of questioning in the survey; Smokers and Recent quitters categories will not add to the overall total because ‘recent quitters’ have been restricted to those who reported quitting within 6 months of the survey; Response rate for each country are for Wave 1 (except for Mexico, where the Wave 2 replenishment response rate is used as a surrogate) and an average of retention rates up to the wave being analyzed are reported above. Sample characteristics (gender and age) are unweighted and all other results are weighted by the rescaled cross-sectional weights; Prevalence estimates were rounded to the nearest whole number; SD = Standard deviation; CI = Confidence interval; N/A = Not available; * Countries where the sale of e-cigarettes containing nicotine is banned or restricted; ** estimated (exact rate could not be obtained); † The question about current use of e-cigarettes was not asked in the survey; ‡ The ‘survey date mid-point’ is the month/year on which 50% of the respondents had successfully completed the survey for that wave. Dates are listed in chronological order (earliest to latest date surveyed).
