Development and Validation of a Dynamic Online Nomogram Prediction Model for Assessing the Risk of Erectile Dysfunction.
Article in The world journal of men's health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeErection dysfunction (ED) represents a globally prevalent men's health problem and affected by a variety of factors. This study aimed to develop a dynamic nomogram model to assess the probability of ED in a population through a multitude of factors. MATERIALS AND
methodsA total of 2,668 subjects from the National Health and Nutrition Examination Survey were included in this study. The entire dataset was randomly divided into training and validation sets, with the training set comprising 70% of the data and the validation set comprising 30%. The Least Absolute Shrinkage and Selection Operator and multivariate logistic regression analysis determined the predictors for constructing the nomogram, and the model was evaluated by Concordance Index (C-index), calibration curve, Hosmer-Lemeshow test, and decision curve analysis.
resultsThe nomogram model consisted of 9 predictors, which were age, education, stroke, lymphocyte, diabetes, poverty income ratio, prostate disease, activity, and hypertension. The C-index for the training set was 0.828 and for the validation set was 0.825, indicating that the model shows good clinical applicability and calibration of the model on both the training and validation sets. Additionally, we created an online dynamic nomogram (https://wvknly-liu-guodong.shinyapps.io/dynnomapp/) that anyone can evaluate on a web page.
conclusionsOur dynamic nomogram can integrate multiple risk factors to provide a personalized risk assessment that is highly clinically predictive and provides a valuable tool for early intervention and prospective management of ED. This could help physicians to identify and manage high-risk populations early and provide personalized treatment plans.
