Amputation and reamputation for dry gangrene of both lower extremities in with chronic kidney disease patients with calciphylaxis accompanied by multidrug-resistant bacterial infections: A case report and literature analysis.
Review in Medicine, 2026. 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
rationaleNephritis can further develop into chronic kidney disease (CKD). CKD with calciphylaxis is mainly manifested as necrotic ulcers of terminal tissues or even gangrene in the skin and distal limbs. Patients with CKD have a high risk of developing multidrug-resistant bacterial infections. PATIENT CONCERNS: Our patient developed dry gangrene of both feet for 1 month, accompanied by complications, such as anemia, hypoproteinemia, and pulmonary infection. The patient had a history of CKD for 30 years, calciphylaxis for 5 years, and multidrug-resistant bacterial infection for 1 month. DIAGNOSES: The patient was diagnosed with atherosclerotic gangrene of the lower extremities (dry gangrene of both feet), multidrug-resistant bacterial infection, pulmonary infection, hypoalbuminemia, anemia (moderate), urinary tract infection, and CKD with calciphylaxis.
interventionsIn this case, the patient underwent a clinical evaluation and was successfully resuscitated. After achieving clinical cure criteria for multidrug-resistant bacterial infection, the patient underwent a mid-calf amputation of both legs under general anesthesia. Half a year post-operation, due to a recurrence of multidrug-resistant bacterial infection, the stumps of the amputated legs ulcerated with bone exposure. While treating multidrug-resistant infection, the patient was pharmacologically treated for CKD. In addition, debridement of the infected wounds and reamputation of both leg stumps were performed. OUTCOMES: Following the reamputation surgery, the patient underwent stump training for 3 months, and then walked on ground with prostheses. LESSONS: Reflections prompted by this case: a textbook approach to treatment (standardized, systematic treatment strategy) is crucial. In this case, the primary objective was to save the patient's life, concurrently alleviating symptoms such as anemia and hypoproteinemia, rigorously combating multidrug-resistant bacterial infection, and performing a mid-calf amputation of both legs. Six months after operation, the recurrence of multidrug-resistant bacterial infection resulted in bone exposure at the stumps of both legs, and the patient had to undergo reamputation of both leg stumps.
