Atypical diabetic foot ulcer turning into squamous cell carcinoma.

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
Cutaneous squamous cell carcinoma (cSCC) may rarely arise in chronic diabetic foot ulcers, particularly at unusual sites. We report an 86-year-old man with a chronic retrocalcaneal ulcer refractory to standard care. Vascular imaging showed peripheral arterial disease, and biopsy confirmed well-differentiated cSCC (AJCC 8th edition: pT2Nx), measuring 2.1 × 1.5 cm with 8 mm invasion depth. Staging positron emission tomography/computed tomography and magnetic resonance imaging showed no evidence of metastasis. The patient underwent vascular optimization, wide local excision with clear margins, and local advancement flap coverage. At 4 months, there was no recurrence or metastasis, and wound healing was durable. To the best of our knowledge, this is the first reported case in Saudi Arabia of cSCC developing from a diabetic foot ulcer in the retrocalcaneal region. This case underlines the importance of early biopsy and multidisciplinary evaluation in atypical, non-healing ulcers to avoid delayed diagnosis and ensure optimal patient outcomes.
