Author Correction

Please note that there is an error in the 5th paragraph, next to last line, in the section DATA SOURCES AND VARIABLES
"ICD10-code K70" should read "100-152, 160-199; ICD10".
The correct paragraph is shown here:

From the school questionnaire, we used the information on IQ and creative potential. The IQ test consisted of spatial, arithmetic and verbal sub-tests. In the spatial test, students were asked to choose one out of four alternative three dimensional figures, corresponding to a flat, two dimensional template. In the arithmetic test, students were to determine the logical sequences for a series of six numbers. In the verbal test, students were to identify, out of four alternatives, the antonym of a given word. Each sub-test included 40 problems, with a correct answer counting for one point, resulting in a range of 0�40 points. The overall test ranged from 0 to 120 points, with the highest value reflecting the best score. In the creativity test, students were to come up with a word that was associated somehow with three other rather different words. This test included 25 different word series, and each correct answer counted for 1 point, giving a scoring range of 0 to 25 points. Cause of death was based on official death certificates coded using the 7th Revision of the International Classification of Diseases for the years 1968�1969, the 8th Revision for 1970�1993, and the 10th Revision for 1994�1998. Cause of death was classified into the following selected end points: CVD (ICD7-codes 330�468; ICD8-codes 390�458; ICD10-codes I00-I52,I60-I99; 100-152, 160-199; ICD10); injuries and suicide (ICD7-codes 800�999; ICD8-codes 800�999; ICD10-codes V01-Y99); and other causes (all other codes).
