Role of C-reactive Protein (CRP) Levels and Glycemic Control in Outcome of Diabetic Foot Ulcer Healing.

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 This study focuses on patients with diabetic foot ulcers (DFUs) to assess the association between inflammatory and glycemic markers and ulcer outcomes. Specifically, serum C-reactive protein (CRP) and glycated hemoglobin (HbA1c) levels were analyzed to evaluate their relationship with wound healing and amputation rates. Methods A cross-sectional observational study was conducted at Sree Balaji Medical College and Hospital, enrolling 123 diabetic patients with clinically confirmed foot ulcers. Demographic data, ulcer classification, fasting and postprandial blood glucose, glycated hemoglobin (HbA1c), and CRP levels were recorded and analyzed to determine their correlation with wound healing and clinical outcomes. Results A strong positive correlation was observed between CRP and HbA1c levels (r = 0.72, p < 0.001), indicating that poor glycemic control is closely associated with systemic inflammation and impaired ulcer healing. Patients with persistently elevated CRP values experienced delayed wound closure, higher rates of secondary infection, and greater amputation risk. In contrast, patients maintaining good glycemic control (HbA1c < 7%) demonstrated faster healing, reduced infection rates, and fewer complications. Importantly, CRP levels >10 mg/L were found to be a reliable predictor of non-healing ulcers and major adverse outcomes, suggesting its potential role as a prognostic biomarker in DFU management. Conclusion The study highlights the dual importance of glycemic control and inflammation regulation in optimizing DFU outcomes. Routine CRP monitoring, when integrated with standard diabetic care, may facilitate early risk stratification, guide timely interventions, and reduce the incidence of limb-threatening complications. Further prospective studies are warranted to validate CRP as a prognostic marker and to assess the potential role of targeted anti-inflammatory therapies in improving DFU healing and preventing amputations.
