Pleural effusion, ascites, colon ulcers and hematochezia: What we can learn from the diagnostic process of a patient with plasma cell myeloma: A case report.
Article in World journal of clinical cases, 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
backgroundPlasma cell myeloma (PCM) is characterized by hypercalcemia, renal impairment, anemia, and bone destruction. While pleural effusion, ascites, abdominal pain, and bloody stool are common manifestations of lung disease or gastrointestinal disorders, they are rarely observed in patients with PCM. CASE SUMMARY: A 66-year-old woman presented with complaints of recurrent chest tightness, wheezing, and abdominal bloating accompanied by bloody stools. Computed tomography revealed pleural effusion and ascites. Pleural effusion tests showed inflammation, but the T-cell spot test and carcinoembryonic antigen were negative. Endoscopy showed colonic mucosal edema with ulcer formation and local intestinal lumen stenosis. Echocardiography revealed enlarged atria and reduced left ventricular systolic function. The diagnosis remained unclear. Further testing revealed elevated blood light chain lambda and urine immunoglobulin levels. Blood immunofixation electrophoresis was positive for immunoglobulin G lambda type. Smear cytology of the bone marrow showed a high proportion of plasma cells, accounting for about 4.5%. Histopathological examination of the bone marrow suggested PCM. Flow cytometry showed abnormal plasma cells with strong expression of CD38, CD138, cLambda, CD28, CD200, and CD117. Fluorescence
conclusionA diagnosis of PCM should be considered in older patients with pleural effusion, ascites, and multi-organ injury.
