Digit Amputation Secondary to COVID-19-Induced Raynaud's Phenomenon.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Raynaud's phenomenon (RP) is characterized by episodic vasospasm of the small blood vessels, primarily affecting the fingers and toes. Management includes lifestyle modifications, pharmacological treatments, and in severe cases, surgical interventions. Here we report a case of an 80-year-old male patient with a history of hypertension, dyslipidemia, obesity, and atrial fibrillation who presented to the emergency department with edema, cyanosis, and intense pain in the fingers of both hands following a mild COVID-19 infection (no dyspnea or hypoxemia). Despite stable vital signs and an otherwise unremarkable physical exam, laboratory tests revealed leukocytosis, elevated inflammatory markers, and signs of local infection. Consequently, he was admitted to the ward on antibiotics (amoxicillin/clavulanic acid), nifedipine for vasodilation, and opioids for pain control. However, his condition deteriorated, with progressive necrosis necessitating escalation of therapy to iloprost infusion and bosentan. The right hand showed no improvement, and surgical intervention was planned around wound care aimed at mummification and subsequent amputation. The left hand gradually improved with continued medication. During hospitalization, serologic testing and nailfold capillaroscopy did not reveal any secondary causes such as connective tissue diseases. Imaging studies ruled out underlying neoplasia and thrombosis. The patient was diagnosed with severe Raynaud's phenomenon, potentially triggered by the recent COVID-19 infection, a phenomenon already described in case reports. This case underscores the potential impact of COVID-19 as a precipitating factor for severe Raynaud's phenomenon, particularly in elderly patients with comorbidities. The rapid progression and refractory nature of the condition highlight the need for early recognition and aggressive management.
