Electrocardiogram abnormalities and CVD mortality: prospective cohort study of Tehran lipid and glucose study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThe incorporation of electrocardiogram (ECG) abnormalities with other clinical indicators can strengthen the hypothesis regarding the improvement of diagnosis and the enhancement of screening accuracy for cardiovascular diseases. This study aimed to determine the risk of mortality from cardiovascular diseases (CVD) based on ECG abnormalities, in addition to other known risk factors, within the Tehran Lipid and Glucose Study (TLGS).
methodsIn this prospective cohort study conducted within the framework of the TLGS, 6,422 individuals aged 30 and older, who had ECG data and no history of cardiovascular disease, were examined over a follow-up period with a median of 18.1 years (IQR: 1.05). Logistic regression models, adjusted for age, gender, abdominal obesity, BMI, high blood pressure, LDL cholesterol levels, fasting blood glucose, smoking status, and education level, were used to estimate the odds ratios (OR) for ECG abnormalities regarding CVD mortality.
resultsOverall, during the 19-year follow-up period, 233 CVD-related deaths occurred, resulting in a cumulative incidence of mortality of 3.63% in the study population. Individuals with Q-wave abnormalities (OR = 2.060, 95% CI: 1.327-3.198, P = 0.001) and T-wave abnormalities (OR = 1.990, 95% CI: 1.327-3.986, P = 0.001) had approximately twice the risk of CVD mortality compared to those without these abnormalities. However, ECG abnormalities such as ST-segment (OR = 1.169, 95% CI: 0.728-1.879, P = 0.518), QRS duration (OR = 0.780, 95% CI: 0.385-1.582, P = 0.492), and PR interval (OR = 1.406, 95% CI: 0.297-6.662, P = 0.668) did not show a significant association with CVD mortality.
conclusionAmong the ECG abnormalities (ST, T, Q, PR, QRS), Q and T abnormalities are associated with CVD mortality. It can be concluded that ECG abnormalities in asymptomatic adults are related to the risk of CVD mortality and can serve as warning factors for the development of mortality from CVD.
