Data collected from surveys included smoking; high blood pressure (diagnosis or use of antihypertensive medications), physical activity, body mass index, education, and alcohol use. Participants were separated into two groups: smokers (occasional or current) or non-smokers (never and former). Current smokers were classified according to the number of cigarettes smoked per day: light, less than 10; moderate, 10-19; heavy, 20 or more.

The analysis of the 120 fatal bleeding events found four fatalities occurred among both twins in two pairs. In the remaining 116 fatalities, one twin died of bleeding in the brain, while the other died of another cause, migrated during the follow-up or was still alive at the end of the study follow-up. Heavy and moderate smokers had three times the risk of fatal bleeding in the brain, while light smokers had slightly less at 2.8 times the risk.

According to the study, the median age at the fatal brain bleed was 61.4 years. Risk factors such as high blood pressure, lower physical activity rates and being female were not found to be significant influences in this investigation, unlike prior studies. "Smoking was associated with fatal bleeding in the brain consistently in both men and women and with bleeding stroke deaths within twin pairs where only one of the twins died from a SAH," the study authors wrote.
