Prospective analysis 1976–1986 including only men who in 1976 had no lung symptoms indicating bronchitis, 𝑛 = 2 , 1 8 3 according to self-assessed salt intake in 1976 and 1985-6 and smoking characteristics. Various forced entry multiple logistic regression analyses using different adjustment criteria.
