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
Objective: This study aimed to evaluate the predictive value of carotid plaque characteristics for ischemic stroke risk in postmenopausal women, and to develop a predictive model based on these features. Methods: A retrospective analysis of clinical and carotid ultrasound data was performed on 145 postmenopausal women admitted to our hospital between January and December 2023. Patients were divided into stroke (n = 23) and non-stroke (n = 122) groups based on ischemic stroke occurrence during follow-up. Carotid plaque characteristics (location, number, echogenicity, surface, internal structure, and calcification) were assessed using color Doppler ultrasound. Cox regression analysis was used to examine plaque morphology's association with ischemic stroke risk. A prediction model incorporating plaque characteristics and traditional risk factors (age, hypertension, diabetes, smoking, dyslipidemia) was developed and evaluated using receiver operating characteristic curve analysis. Results: Cox regression analysis revealed several plaque characteristics as independent risk factors for ischemic stroke. These included hypoechoic plaques (hazard ratio (HR) = 2.16), irregular surfaces (HR = 1.84), ulcerated plaques (HR = 3.25), and heterogeneous internal structures (HR = 1.92). Additionally, plaques located in the internal carotid artery (HR = 2.31) and the presence of multiple plaques (≥3) (HR = 1.86) were significant stroke risk factors. The predictive model combining these plaque features with traditional risk factors demonstrated superior accuracy (area under the curve (AUC) = 0.87) compared to models based solely on traditional risk factors (AUC = 0.73, P = 0.008). Stratification using the prediction model identified low, moderate, and high-risk groups, with stroke incidence highest in the high-risk group (35.9%) compared to moderate (12.1%) and low-risk (4.2%) groups. Conclusion: Carotid plaque morphology is a significant predictor of ischemic stroke in postmenopausal women. Including plaque characteristics in risk assessments improves predictive accuracy, aiding in early identification and personalized prevention strategies.
