External validation of the American heart association's PREVENT equations in predicting atherosclerotic cardiovascular disease risk among Arab women and men: a retrospective cohort study.
Article in BMC cardiovascular disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundCardiovascular disease (CVD) prediction models are important tools for identifying individuals at risk and guiding preventative strategies. However, before new prediction models can be used in clinical practice, it is vital to validate them in the specific population they are intended to serve. Despite the high burden of CVD in Arab populations, they remain underrepresented in model development and validation studies. This study aimed to externally validate the performance of the newly released PREVENT models, originally developed in a United States population, among UAE nationals.
methodsThis study included 897 Emirati participants aged 30-79 from Tawam Hospital, UAE, with no prior CVD history. Data were collected from April to December 2008, with follow-up on atherosclerotic CVD (ASCVD) events until January 2020. The study compared the 10-year ASCVD risk using the PREVENT-ASCVD Base and PREVENT-ASCVD HbA1c equations, assessing discrimination and calibration using C-index values and calibration plots.
resultsThe Emirati cohort had a mean age of 52 years, with 50% female participants. Over a median follow-up of 10.4 years for females and 10.1 years for males, 8.2% of females and 13.4% of males experienced ASCVD events. The PREVENT equations demonstrated good discrimination in females (C-index: 0.81-0.82) but moderate discrimination in males (C-index: 0.70-0.72), with calibration plots indicating overestimation at lower risk levels and underestimation at higher levels, especially in males. At the 7.5% risk cut-off, sensitivity and specificity were suboptimal in males but performed well in females.
conclusionsWhile the PREVENT equations predicted ASCVD risk effectively in Emirati women, recalibration is needed for better accuracy. These findings support the use of the PREVENT models for CVD prevention in the UAE, particularly for women.
trial registrationThis study is a retrospective observational study that utilizes existing data. As such, it does not involve the prospective assignment of participants to interventions, nor does it meet the criteria for a clinical trial. Therefore, trial registration is not applicable to this research.
