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: To explore the influencing factors of left ventricular diastolic dysfunction (LVDD) in maintenance hemodialysis (MHD) patients and construct a nomogram prediction model. Methods: Data was collected from 357 patients who received MHD treatment in our hospital from April 2022 to December 2024. According to a 7:3 ratio, the patients were grouped into a modeling group of 250 cases and a validation group of 107 cases. The modeling group was grouped into LVDD group of 61 cases and non LVDD group of 189 cases based on whether LVDD occurred. Multivariate logistic regression was used to analyze the risk predictive factors of LVDD in MHD patients in the modeling group. R software was used to draw nomograms. The calibration curve and Hosmer-Lemeshow goodness of fit test were used to evaluate the calibration of the nomogram. The receiver operating characteristic (ROC) curve was used to evaluate the discriminative power of the nomogram. Clinical decision curve analysis (DCA) was used to evaluate the clinical utility of nomograms. Results: Age, left ventricular hypertrophy, hypertension, diabetes, LVMI and hemoglobin were risk predictors of LVDD in MHD patients ( Conclusion: The nomogram prediction model constructed in this study can help clinicians identify LVDD high-risk patients in MHD and improve management strategies.
