Prospective Associations of Obesity and Obesity Severity With 9 Cardiovascular Outcomes: The Cross-Cohort Collaboration.
Article in Circulation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundObesity is an established risk factor for cardiovascular disease (CVD); however, the overall and sex-specific relationships across the full spectrum of body mass index (BMI), particularly severe obesity defined as class 2 (BMI 35 to <40.0 kg/m
methodsWe included 289 875 participants (mean age, 60.3 years; 79.2% women) from 21 cohorts of the Cross-Cohort Collaboration enrolled between 1948 and 2015 with harmonized BMI data, a BMI ≥18.5 kg/m
resultsOver 19.2 median years (25th, 11.6; 75th, 23.5 percentile) of follow-up, there were a total of 15 542 incident MI events, 15 467 incident stroke events, 14 172 incident HF events, 9066 diagnosed AF, and 113 918 total deaths, of which 14 647 were CHD-related and 28 879 were CVD-related. Overall, compared with individuals with normal weight, those with class 2 and class 3 obesity had the highest risk of HF (HR, 2.1, 95% CI, 2.0-2.3, and HR, 3.0, 95% CI, 2.7-3.2, respectively) and AF (HR, 1.8, 95% CI 1.7-2.0, and HR, 2.8, 95% CI, 2.5-3.1, respectively). Compared with men, women experienced higher relative increases in the risk associated with severe obesity for outcomes stroke, CVD, and all-cause mortality (P for interaction: <0.001, 0.003, and <0.001, respectively). Furthermore, in men, no increase in stroke risk was observed with higher BMI categories (P trend=0.49), whereas in women, the risk of stroke plateaued across obesity subclasses (compared with normal weight) yet remained significantly increased.
conclusionsHigher BMI was robustly associated with increased risk for most outcomes, particularly HF and AF, even after adjusting for traditional risk factors. Observed sex differences in the relative hazard of higher BMI categories and stroke, total CVD, and all-cause mortality suggest potential differences in underlying biological mechanisms.
