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
backgroundAccurate and rapid assessment of fluid status of maintenance hemodialysis (MHD) patients and maintaining fluid balance is essential to ensure the quality of dialysis treatment. Currently, clinical methods for assessing ultrafiltration volume are still insufficient, and reliable tools that are more accurate and rapid are needed. The objective of this study was to construct a model for predicting ultrafiltration volume (UF) in MHD patients based on artificial neural network (ANN) algorithms, to validate and evaluate this model, and to investigate the impact of body composition prior to dialysis on UF in MHD patients.
methodsA total of 319 patients undergoing MHD treatment at our center were enrolled. Basic demographic and clinical characteristics were collected and evaluated using the hemodialysis information system. Body composition was measured on ≥ 3 separate days before dialysis treatment using an Inbody bioimpedance instrument. The target ultrafiltration volume was determined by nephrologists based on the integration of body composition measurements and clinical characteristics, yielding a dataset of 1,205 entries. Heat maps were used to demonstrate the correlation between body composition and UF in MHD patients, and LASSO regression and multifactorial linear regression were used to screen the relevant indicator factors for final inclusion in the model, and Backpropagation Neural Network model (BPNN) was developed using the MATLAB (R2022a) neural network toolbox to establish the projected relationship between UF and pre-dialysis body composition. The effectiveness of the model was assessed based on the coefficient of determination (R

conclusionThis study effectively demonstrates the predictive role of an artificial neural network model based on pre-dialysis body composition information in estimating ultrafiltration providing a valuable predictive tool to optimize assessment volume for MHD patients, of ultrafiltration volume in MHD patients.
