Relationship and predictive value of controlling nutritional status score and serum vitamin level with coronary heart disease in young and middle-aged adults.
Article in BMC nutrition, 2025. 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
objectiveTo investigate the relationship between CONUT score and serum vitamin (25-OHD, folic acid, vitamin B12) levels and CHD in young and middle-aged adults, and to analyze the value of CONUT score combined with serum vitamin (25-OHD, folic acid, vitamin B12) levels in predicting the risk of CHD in young and middle-aged adults.
methodsThis study was a retrospective case–control study. A total of 135 young and middle-aged patients with CHD diagnosed by coronary angiography in Tangshan Workers’ Hospital from April 2023 to October 2024 were selected as the case group (n = 135), and 120 patients with negative coronary angiography or CTA results in our hospital during the same period were selected as the control group (n = 120). The nutritional status of the subjects was evaluated by CONUT score, and the serum vitamin level of the subjects was detected by chemiluminescence method. Univariate and multivariate Logistic regression analysis were used to analyze the relationship between different nutritional status levels, serum vitamin levels and CHD in young and middle-aged people. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of CONUT score combined with serum vitamin level for the risk of CHD in young and middle-aged adults.
resultsThe detection rate of malnutrition in the CHD group was 48.90%, and the detection rate of malnutrition in the control group was 30.80%. The multivariate results show that according to the unadjusted model, there was a significant relationship between high CONUT score, low 25-OHD, low folic acid, and low serum vitamin B12 levels and CHD. In multifactor models 2, after adjusting for gender, family history of premature CHD, history of hypertension, history of diabetes, history of smoking, LDL-C, Hcy, CRP, blood glucose, blood uric acid, serum creatinine and other traditional risk factors of CHD, it was found that CONUT score ≥ 2 points, serum 25-OHD ≤ 17.20 ng/ml, folic acid ≤ 10.90 ng/ml, serum vitamin B12 ≤ 485.50 pg/ml, the risk of CHD was higher. ROC curve analysis showed that CONUT score combined with three serum vitamins, AUC was 0.836(95%CI:0.788–0.884), the sensitivity and specificity were 83.7% and 69.2%(P < 0.05).
conclusionThe detection rate of nutritional imbalance in young and middle-aged patients with CHD is high, and there is a significant relationship between nutritional status and serum vitamin level and the risk of CHD in young and middle-aged patients. CONUT score and serum vitamin level can be used as indicators to evaluate the risk of CHD in young and middle-aged people.
