A Multi-Center Prospective Study on the Healing of Neuro-Ischemic Ulcers in Singapore: A Prospective Cohort Study.

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
Background and Aims: Neuro-ischemic ulcers (NIU) present a substantial clinical and economic burden on the healthcare systems. This study aims to evaluate their healing rate, associated healthcare resource utilization, and prognostic factors influencing healing. Methods: Consecutive patients attended specialist clinics or admitted to wards in three tertiary hospitals for new or existing NIUs from November 2019 to November 2021 were eligible for this study. Each participant was followed up three times (1-month, 3-month and 6-month after enrollment), with ulcer healing as the primary outcome of interest. Cox regression analysis was performed to identify independent predictors of NIU healing. Results: In total, 439 patients were recruited. Six months after they seek care in the tertiary healthcare setting, 36.0% of the participants had their ulcer fully healed. Male gender (adjusted HR: 0.71, 95% CI: 0.53-0.93), history of coronary intervention (adjusted HR: 0.62; 95% CI: 0.41-0.93), requirement of lower extremity revascularization (adjusted HR: 0.72; 95% CI: 0.54-0.98) and offloading (adjusted HR: 0.61; 95% CI: 0.46-0.81) were found to be associated with failure to heal. Ulcers located over the toes (adjusted HR: 1.64; 95% CI: 1.17-2.32) was associated with better healing. Dependent activity of daily living (adjusted HR: 0.74; 95% CI: 0.55-1.01) was also potentially a risk factor for slow healing with borderline significance.Nonhealed group of patients incurred higher requirement of revascularization (42.3% vs. 25.3%, Conclusion: NIU imposes a significant burden on both patients and the healthcare system in Singapore, with low healing rates even after 6 months of tertiary-level care. Early identification and risk stratification of high-risk patients may help improve outcomes.
