Evaluation of the hypercholesterolemia care cascade and compliance with NCEP-ATP III guidelines in Iran based on the WHO STEPS survey.

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
introductionNoncommunicable diseases (NCDs), particularly cardiovascular disease (CVD), are the leading cause of death worldwide, with hypercholesterolemia being a major risk factor for CVD. This study evaluated the hypercholesterolemia care cascade in Iran-including prevalence, diagnosis, treatment coverage, and effectiveness-using the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) guidelines.
methodsThis cross-sectional study drew on data from the 2021 Iran STEPS survey, which employed a systematic cluster sampling of adults aged ≥ 18 years across all provinces in Iran. Hypercholesterolemia was defined per NCEP-ATP III thresholds (LDL ≥ 160 mg/dL, total cholesterol ≥ 240 mg/dL, HDL ≤ 40 mg/dL, or ongoing lipid-lowering therapy). Weighted descriptive statistics were calculated, and Poisson regression with robust variance estimated crude and adjusted prevalence ratios for optimal lipid control among those treated. The 10-year CVD risk was determined using the Framingham Risk Score, stratifying participants into low (< 10%), intermediate (10-20%), and high (> 20%) risk categories.
resultsOut of 18,074 participants, 10,582 (55.32%, 95% CI: 54.29-56.35) met NCEP-ATP III criteria for hypercholesterolemia. Among these, only 20.61% (19.55-21.72) were receiving pharmacological treatment. Treatment coverage was notably lower in males (13.15%, 11.98-14.40) than females (29.12%, 27.35-30.96). Statins were the most commonly used medication (11.43% of males, 25.87% of females). Of those receiving treatment, 52.85% (females) and 53.93% (males) achieved optimal LDL, while 76.98% (females) and 81.06% (males) attained total cholesterol < 200 mg/dL. However, only 19.89% (females) and 3.97% (males) met the HDL > 60 mg/dL goal. The 10-year CVD risk was < 10% in 57.79% of participants, 10-20% in 33.27%, and > 20% in 8.94%.
conclusionDespite a high prevalence of hypercholesterolemia in Iran, treatment coverage remains suboptimal, particularly among males and working-age adults. Although most treated individuals achieve favorable LDL and total cholesterol levels, gaps persist in achieving optimal HDL targets. These findings underscore the need for strengthened screening, treatment, and adherence strategies-alongside broader preventive measures-to reduce the burden of hypercholesterolemia and CVD in Iran.
