The coefficient of year = 0.1006, p < 0.001 among all surveys; greater than zero suggesting positive changes from 1990 to 2010, lower suggesting the opposite. The coefficient of year = 0.0974, p < 0.001 among Dutch surveys. The coefficient of year = 0.1162, p < 0.001 among Belgian surveys. See Appendix 3 for regression coefficients
