Establishing a nomogram for predicting the risk factors for delayed bleeding after endoscopic submucosal dissection for colorectal tumors.
Article in International journal of colorectal disease, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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 aim of this study is to establish a nomogram that can predict the risk factors for delayed bleeding after endoscopic submucosal dissection (ESD). This model can be used to assess the probability of delayed bleeding before ESD surgery, thereby avoiding wasting medical resources and improving patient satisfaction.
methodsThis was a retrospective study in which all patients underwent ESD surgery for colorectal tumors between August 2021 and February 2024. Patient demographics and surgical characteristics were collected. All patients were randomly divided into a training set and a testing set. Univariate and multivariate regression analyses of the training set revealed the independent risk factors for delayed bleeding after ESD. These independent risk factors were used to construct a nomogram model. This model was validated using internal validation methods such as the C-index, calibration curve, and decision curve analysis.
resultsThis study included 587 patients. The occurrence rate of delayed bleeding after ESD in the training set was 8.98%. Multivariate regression analysis revealed that the location of the lesion in the rectum, a large lesion, and a prolonged surgery time were independent risk factors for delayed bleeding after ESD. The C-index for this model was 0.89, and validation of this nomogram model demonstrated good consistency between the predicted and actual values.
conclusionMultivariate regression analysis revealed the independent risk factors for delayed bleeding after ESD, and a nomogram with a relatively consistent accuracy was established. The clinical application of this model can reduce the incidence of delayed bleeding and therefore improve patient healing.
