1 · What the graph read from it

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.

2 · The registry

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

This report describes the case of a 57-year-old man who developed squamous cell carcinoma (SCC) on his right thumb 10 years after a traumatic injury. The lesion, initially misdiagnosed as osteomyelitis, persisted despite antibiotic treatment. We suspected a neoplasm, such as a Marjolin's ulcer, which is an SCC that develops long after trauma, including burn scars, and we therefore performed a biopsy of the lesion. A biopsy confirmed SCC with bone invasion but no vascular involvement. The patient underwent a proximal phalanx amputation and ipsilateral axillary sentinel lymph node biopsy (SLNB), which was negative. SCC of the hand has a higher rate of recurrence and metastasis than other sites, emphasizing the need for early diagnosis and appropriate treatment. Delayed detection, as in this case, may lead to more aggressive interventions. Surgical margins of at least 1 cm are recommended for tumors larger than 2 cm in diameter. SLNB can aid in prognostication. Physicians should be aware of the potential for SCC in post-traumatic lesions to avoid misdiagnosis and ensure timely intervention to improve patient outcomes. No recurrence was observed four years after surgery.
