Waterpipe smoking and risk of cardiovascular disease mortality: Findings from a Prospective Cohort Study.
Article in American journal of preventive cardiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Little is known about the role of waterpipe smoking and cardiovascular (CVD) risk. We evaluated the association between ever-smoking waterpipe and risk of death from incident CVD using data from the Hanoi Prospective Cohort Study, a prospective cohort study in Northen Vietnam. Methods: The current analysis included 35,646 Vietnamese aged 18 years and older who were recruited during 2007-2019 period. Cox proportional hazard regression model was used to calculate the hazard ratio (HR) and 95% confidence intervals (95% CIs) for risk of CVD mortality related to ever-smoking waterpipe. Results: After a median follow-up of 11.01 years (range: 0.13-11.64 years), we identified 344 CVD deaths. Overall, compared with never-smokers, ever-WTP smokers were about 60% higher risk of CVD deaths (HR=1.57; 95% CI: 1.16-2.13), 44% higher risk of deaths from cerebrovascular disease (HR=1.44; 95% CI: 1.08-1.93) and the highest of CVD deaths was among dual ever-smokers of waterpipe and cigarette (HR=1.77, 95% CI: 1.21-2.60). Also, compared with non-smokers & no alcohol user, the CVD risk was the highest among WTP smokers who smoked ≥11 pack-years (i.e., 1 pack/day x11 years) & ever-alcohol drinkers (HR=2.19, 95% CI: 1.42-3.38). Conclusion: In a large prospective cohort study, we showed that ever-waterpipe smoking was associated with increased risk of CVD deaths, particularly deaths from cerebrovascular disease; and higher among dual smokers of cigarettes and waterpipe. Additionally, smoking cigarette and drinking alcohol doubled risk of CVD death. These findings suggest that waterpipe smoking should receive equal attention as cigarette smoking in tobacco control and prevention programs.
