Risk Factors and Nomogram Model for Multidrug-Resistant Bacterial Infections in Diabetic Foot Wounds.
Article in International wound journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
To study the risk factors associated with multidrug-resistant bacteria (MDRB) infection in diabetic foot (DF) wounds and to develop a nomogram model to predict the risk of MDRB infection in patients with DF. A total of 157 patients with DF between January 2013 and December 2023 were included in this study. A retrospective analysis was conducted to examine the characteristics of MDRB infections. Univariate and multivariate logistic regression analyses were performed to identify risk factors associated with MDRB infection. Based on these risk factors, a predictive model was built using R software and a nomogram was constructed. Multivariate logistic regression analysis revealed that the wound area, previous hospitalization, prior use of antibacterial agents, lower extremity ischaemia grade, and hypoproteinaemia were independent risk factors for MDRB infection in DF wounds (p < 0.05). Construction of the nomogram model for MDRB infection in DF wounds: A nomogram model was developed using five identified risk factors-wound area, previous hospitalization, previous use of antibacterial drugs, lower extremity ischaemia grade and hypoproteinaemia-as predictors. The area under the receiver operating characteristic (ROC) curve (AUC) was 0.863. The model has a good ability to predict MDRB infections in DF wounds. Wound area, previous hospitalization, previous use of antibacterial drugs, lower extremity ischaemia grade and hypoproteinaemia were identified as independent risk factors for MDRB infections in DF wounds. The nomogram model constructed on the basis of these five factors demonstrated good predictive performance for MDRB infection.
