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
objectiveTo evaluate the impact of diabetic foot ulcers (DFUs) on mortality risk in a Brazilian cohort of individuals followed at an association of people living with diabetes mellitus. SUBJECTS AND
methodsThis retrospective, population-based epidemiological study assessed the impact of DFUs on mortality risk in a cohort of Brazilian individuals with types 1 and 2 diabetes mellitus. Data were obtained from medical records covering the period from 1990 to 2024 and included sociodemographic, clinical, laboratory, and therapeutic variables. Survival analyses were conducted using Cox proportional hazards models, with death as the event of interest, and were adjusted for potential confounders.
resultsAmong the 382 participants included in the final analysis, DFUs, amputations, and diabetic peripheral neuropathy were associated with increased mortality risk by 89%, 123%, and 37%, respectively. Peripheral artery disease showed a modest, but not statistically significant, increase in mortality risk. Patients with DFUs who were not using oral antidiabetic drugs had a 165% higher mortality risk, and those with prior amputations and poor fasting glucose levels had a 41% increased mortality risk.
conclusionOverall, DFUs were identified as critical predictors of mortality in people living with diabetes mellitus, mostly among those with type 2 diabetes mellitus. The impact of DFUs on mortality risk is multifaceted and context-dependent, highlighting the leading role of prior amputations. These findings underscore the need for targeted early interventions and the implementation of strategies aimed at reducing mortality in this high-risk population.
