Abstract

BACKGROUND: The prevalence of smoking in diabetic patients remains high, and reliable quantification of the excess mortality and morbidity risks associated with smoking is important for diabetes management. We performed a systematic review and meta-analysis of prospective cohort studies to evaluate the relation of active smoking with risk of total mortality and cardiovascular events among diabetic patients. METHODS AND RESULTS: We searched Medline and Embase databases through May 2015, and multivariate-adjusted relative risks were pooled by using random-effects models. A total of 89 cohort studies were included. The pooled adjusted relative risk (95% confidence interval) associated with smoking was 1.55 (1.46-1.64) for total mortality (48 studies with 1,132,700 participants and 109,966 deaths), and 1.49 (1.29-1.71) for cardiovascular mortality (13 studies with 37,550 participants and 3163 deaths). The pooled relative risk (95% confidence interval) was 1.44 (1.34-1.54) for total cardiovascular disease (16 studies), 1.51 (1.41-1.62) for coronary heart disease (21 studies), 1.54 (1.41-1.69) for stroke (15 studies), 2.15 (1.62-2.85) for peripheral arterial disease (3 studies), and 1.43 (1.19-1.72) for heart failure (4 studies). In comparison with never smokers, former smokers were at a moderately elevated risk of total mortality (1.19; 1.11-1.28), cardiovascular mortality (1.15; 1.00-1.32), cardiovascular disease (1.09; 1.05-1.13), and coronary heart disease (1.14; 1.00-1.30), but not for stroke (1.04; 0.87-1.23). CONCLUSIONS: Active smoking is associated with significantly increased risks of total mortality and cardiovascular events among diabetic patients, whereas smoking cessation is associated with reduced risks in comparison with current smoking. The findings provide strong evidence for the recommendation of quitting smoking among diabetic patients.

  • Various forms of tobacco exposure continue to contribute to excess cardiovascular and other causes of death in multiple parts of the world.

    “Various forms of tobacco exposure continue to contribute to excess cardiovascular and other causes of death in multiple parts of the world.”

    From KDIGO 2022 Clinical Practice Guideline for Diabetes Management in Chronic Kidney Disease (2022) · cites this paper as [184]

    The Results (Absolute risk difference and population attributable fraction; page unavailable) estimate excess total and cardiovascular mortality attributable to active smoking among patients with diabetes worldwide, with examples from the US, UK and China. The claim extends this finding to various forms of tobacco exposure and does not retain the restriction to patients with diabetes; the paper does not establish those broader points. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
