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
objectivesIntravascular large B-cell lymphomas are a rare group of extranodal non-Hodgkin's lymphomas with no apparent specificity of symptoms and often a poor prognosis. This study aims to investigate the clinical features and imaging manifestations of intravascular large B-cell lymphoma, to improve the awareness of clinicians and imaging physicians and to reduce the underdiagnosis and misdiagnosis of this disease.
methodsFive patients with pathologically confirmed intravascular large B-cell lymphoma diagnosed between December 2011 and February 2022 at Xiangya Hospital of Central South University were retrospectively analyzed for clinical features and imaging manifestations.
resultsThe age range for the 5 patients in this paper was 44-72 years at an average of (55.4±11.2) years, 2 were male and 3 were female. There were 4 patients with fever, 3 patients with cough, 3 patients with fatigue, and 2 patients with neurological symptoms. The primary sites of lesions were bilateral adrenal glands (2 cases), liver (1 case), central nervous system (1 case), lung (1 case). Imaging of the corresponding site was performed in 5 cases. When the primary site is the adrenal gland, it appears as bilateral adrenal masses or bilateral adrenal thickening with clear contours. When the primary site is the liver, it appears as a hypodense lesion in the right lobe of the liver with "vascular floating sign". When the primary site is the central nervous system, it appears as multiple tumor-like lesions in the frontal-parietal-occipital lobe, right temporal lobe and bilateral cerebellar hemispheres with multiple hemorrhages within the lesions. When the primary site is the lung, it appears as multiple ground glass shadows and solid changes in both lungs with localized lobular septal thickening. The final pathological diagnosis was intravascular large B-cell lymphoma in all 5 patients, one of whom had a good prognosis after chemotherapy, 2 of whom died within 3 days of discharge, and two of whom were lost to follow-up.
conclusionsIntravascular large B-cell lymphoma can involve multiple tissues and organs, and its prognosis is often poor, and its imaging manifestations possess certain specificity. When this disease is highly suspected, a biopsy of the corresponding organ should be performed as soon as possible to clarify the diagnosis.
