represents the statistical significance of the overall relationship between the covariates and smoking history and suicidal ideation status respectively.
represents a statistically significant difference (p<0.05) between never smokers and current smokers
represents a statistically significant difference (p<0.05) between former smokers and current smokers
represents a statistically significant difference (p<0.05) between never smokers and former smokers
Cochran Armitage Trend Test >0.05
Of individuals at baseline; 44.5% of Non-smokers, 43.2% of Current smokers, and 44.2% of Former smokers (χ2 (df=2)=0.437; p=0.804) were lost to follow-up in 1993/4.
33.9% of individuals aged 18-29, 30.8% of individuals aged 30-44, 41.6% of individuals aged 45-64, and 70.0% of individuals aged 65 and older were lost by wave 3 (χ2 (df = 3) = 354.13; p=0.0001)
46.5% of men and 43.8% of women were lost from baseline and wave 3 (χ2(df=1)=2.42; p=0.120).
