Postoperative Pyoderma Gangrenosum (PPG) After Appendectomy: A Case Report.
Article in Cureus, 2023. 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
Pyoderma gangrenosum (PG) is a rare, poorly understood, non-infectious, autoimmune phenomenon. It is an inflammatory neutrophilic dermatosis characterized by hyperactivity of the skin and the development of papules and pustules that rapidly progress to painful ulcerations with a violaceous and necrotic border. Approximately three to six cases of PG per million of the population occur per year and in the case of postoperative pyoderma gangrenosum (PPG), it is only one to three cases per million operated people. We are presenting a 41-year-old patient with a clinical presentation of PPG, developed in the surgical site on the sixth postoperative day (POD 6) following open appendectomy for acute appendicitis. Initial treatment was for surgical site infection (SSI) with wound opening, regular dressings, and broad-spectrum antibiotics. Due to unresponsiveness to therapy and the unexpected postoperative course with the progression of skin lesions, we suspected PPG. Corticosteroid therapy was introduced in a shock dose, once daily intravenous (IV), with superb results and stopping the spread of the process after only two days. Considering the rarity of PPG, especially when it first occurs postoperatively, we believe that the image of skin changes with superficial spreading and characteristic violaceous ulcerations can be of crucial importance for early diagnosis. A multidisciplinary approach with a mandatory examination by a dermatologist is important in order to make an early diagnosis and prevent wrong treatment, with the potential worsening of the patient's condition. Atraumatic wound care and negative pressure wound therapy are recommended. Patients at risk should perioperatively receive corticosteroids and postoperatively be closely observed for the potential development of PPG. Debridement is not recommended, and surgical treatment and further tissue trauma are undesirable and even prohibited.
