Predicting Diabetic Foot Ulcer Outcomes: Machine Learning-Based Refinement of IWGDF-Approved Classifications for Outpatient Services.
Article in Endocrinology, diabetes & metabolism, 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
introductionThis study aimed to validate and compare six IWGDF-approved classification systems for predicting poor prognostic outcomes in diabetic foot ulcers (DFUs), using the same sample in Iran. We also proposed modifications to enhance the performance and feasibility of these tools, in outpatient setting.
methodsA prospective cohort study was conducted involving 616 DFUs from 400 patients over a six-month period. We assessed the performance of six wound classification systems: Wagner, UTWCS, PEDIS/IDSA, SINBAD, WIFI, and DiaFORA. We adjusted for the key variables associated with poor outcomes that could affect the performance of these systems, employing ten machine learning techniques along with the Least Absolute Shrinkage and Selection Operator (LASSO) and random forest methods for feature selection methods.
resultsOur findings indicated that both the SINBAD and UTWCS systems exhibited comparable effectiveness in predicting outcomes, significantly surpassing other systems. Notably, modifications to the WIFI system-specifically, redefining the wound depth classification to a clearer category-yielded improved predictive capabilities, outperforming the existing systems like SINBAD and UTWCS in predicting poor prognostic outcomes in outpatient setting.
conclusionSINBAD and UTWCS systems yield the best performance in our samples. Our proposed modification on the WIFI system can enhance its applicability for outpatient services according to reported performances.
