Individuals with the metabolic syndrome without diabetes and/or hypertension: which risk factors should healthcare workers pay extra attention to? A longitudinal, cross-sectional study.
Article in BMJ open, 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
objectivesTo examine the metabolic syndrome (MetS) and its components as risk factors for a cardiovascular (CV) event, in individuals without diabetes and/or hypertension, and to explore which of the risk factors are the most predictive for cardiovascular disease (CVD) and whether the assessment of risk could be simplified.
designA longitudinal, cross-sectional study.
settingA randomly selected population.
participantsIn 2002-2005, 2816 randomly selected residents of Skaraborg, Sweden, underwent physical examinations and blood tests as part of the Skaraborg Project. Exclusion of individuals with diabetes mellitus and/or hypertension at baseline left 2328 persons for analyses. OUTCOME MEASURES: CV events were assessed in 2011 using national Swedish registers.
resultsA total of 293 (13%) were defined as having the MetS according to the National Cholesterol Education Programme (NCEP) and 292 according to the International Diabetes Federation (IDF) definition, whereof 27 had a CV event after a mean follow-up time of 9.7 years. The MetS according to NCEP was significantly predictive of a CVD with an HR 2.4 (95% CI 1.4 to 3.9) but not according to the IDF definition. Blood pressure was significantly predictive according to both definitions (HR 1.77, 95% CI 1.06 to 2.97). Also, triglycerides (Tg) were significantly predictive for a CV event (HR 2.05, 95% CI 1.17 to 3.59). Neither waist circumference, high-density lipoprotein nor fasting plasma glucose was predictive for a CV event. Combining a blood pressure ≥125/≥80 mm Hg with Tg ≥1.5 mmol/L was predictive for CVD (HR 2.1, 95% CI 1.3 to 3.6) with a sensitivity of 32.5% and numbers needed to examine (NNE) 7.1. Lowering the cut-off for Tg to ≥1.2 mmol/L (HR 2.1, 95% CI 1.3 to 3.4) increased sensitivity to 44.9% and NNE became 8.
conclusionsUsing blood pressure combined with Tg was shown to be an equally good predictor for CVD as the complete MetS in individuals without diagnosed diabetes or hypertension. Therefore, healthcare personnel should pay attention to individuals with a borderline blood pressure, and if equivalent to or equal to 125/85, continue with measuring Tg for a discussion concerning lifestyle.
