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
BACKGROUND Granulocytic sarcoma, or 'chloroma,' due to extramedullary acute myeloid leukemia (AML) or due to acute myelomonocytic leukemia (AML M5), is rare and is associated with a poor prognosis. This report is of a case of granulocytic sarcoma of the gallbladder and describes the approach to diagnosis and treatment. CASE REPORT A 74-year-old Hispanic woman from Ecuador presented to the emergency department with a five-day history of fever, jaundice, and right upper quadrant abdominal pain. The right upper quadrant ultrasound showed a thickened gallbladder wall with cholelithiasis, a positive sonographic Murphy sign, and marked dilatation of the common bile duct, which was up to 17 mm in diameter. Endoscopic retrograde cholangiopancreatography (ERCP) showed purulence and a stone in the common bile duct, which was removed. She underwent laparoscopic cholecystectomy which identified gangrenous cholecystitis. Despite cholecystectomy and treatment with broad-spectrum antibiotics, she remained febrile with a leukocytosis of up to 80,000 cells/µL. Histopathology of the gallbladder showed infiltrating myeloblasts within the mucosa, submucosa, and muscularis consistent with a granulocytic sarcoma associated with gangrenous cholecystitis due to cholelithiasis. Immunohistochemistry, using a panel of antibodies to CD33, CD68, HLA-DR, and lysozyme, supported the diagnosis of granulocytic sarcoma or extramedullary acute myelomonocytic leukemia (AML M5). CONCLUSIONS A rare case of an extramedullary hematologic malignancy, granulocytic sarcoma of the gallbladder is presented, which highlights the importance of timely diagnosis and treatment, due to the high mortality rate associated with granulocytic sarcoma, or extramedullary AML.
