Pulmonary manifestations of POEM syndrome: a retrospective analysis of 282 cases.
Article in BMC pulmonary medicine, 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
backgroundPolyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome is a rare multisystemic clonal plasma cell disorder. Pulmonary involvement is frequently found in patients with POEMS syndrome, manifesting various clinical features. Therefore, to improve diagnostic accuracy and provide treatment strategies, a comprehensive analysis of pulmonary manifestations of POEMS syndrome is needed.
methodsThis retrospective study included patients with POEMS syndrome at Peking Union Medical College Hospital, a major referral medical center in China, between June 1, 2013, and June 1, 2023. Demographic data, laboratory findings, pulmonary function test results, echocardiograms, and chest imaging data were extracted. Continuous variables were compared using the t-test or Mann-Whitney method. Pearson's chi-square test or Fisher's exact test was conducted to compare categorical data.
resultsOverall, 282 individuals diagnosed with POEMS syndrome were included in this study, of which 56% were male with an average age of 48.7 years. Respiratory symptoms were found in 40.1% of the patients, with dyspnea as the most common symptom (34.4%). Chest computed tomography and echocardiography findings showed that 56.4% of patients exhibited pleural effusion, 62.8% displayed mediastinal or hilar lymphadenopathy, 46.5% presented pleural thickening, 27.3% demonstrated bone lesions of the ribs or thoracic vertebra, 7.8% showed lung interstitial abnormalities, and 35.5% had pulmonary hypertension. Decreased diffuse capacity and restrictive ventilatory patterns were identified in 85.2% (115 cases) and 47.4% (64 cases) of patients, respectively. Patients with respiratory symptoms exhibited higher declined lung function measures than those having no respiratory symptoms. High-risk patients with poor prognosis showed more pulmonary function abnormalities.
conclusionAbnormalities in pulmonary manifestations constitute the significant features of POEMS syndrome. Several patients with POEMS syndrome presented with respiratory symptoms at the initial evaluation. These findings underscore the importance of early identification and accurate diagnosis of POEMS syndrome by clinicians, particularly in cases involving lung and multisystem.
