Characteristics of hospitalized dermatomyositis patients with underlying malignancy: a nationally representative retrospective cohort study.
Article in Archives of dermatological research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
introductionLittle is known regarding characteristics of hospitalized dermatomyositis (DM) patients. Understanding the unique characteristics of hospitalized DM patients with underlying malignancy is important in guiding development of specific work-up and treatment algorithms.
objectivesWe aim to characterize the inpatient burden of DM patients with malignancy (DM malignancy), determine unique characteristics of DM-malignancy inpatients, and assess trends and predictors of cost of care and length of stay for hospitalized DM-malignancy patients.
methodsHospitalized DM patients with and without malignancy were characterized and compared using 2009-2015 National Inpatient Sample. Associated malignancies, risk factors for malignancy, and trends/predictors for cost of care and length of stay were evaluated using multivariable models.
resultsPrevalence of malignancies among hospitalized DM inpatients was 10.9%. Age > 40 years and female sex were significantly associated with increased malignancy risk in DM inpatients. Numerous malignancies were significantly more common in men with DM compared to women, including bronchial, non-Hodgkin's lymphoma, head/neck, bladder, esophageal, kidney, and stomach. The most common malignancies in women with DM were breast and ovarian. Head/neck carcinomas were more common in hospitalized DM patients than previous cohorts evaluating outpatients. Socioeconomic characteristics differed between DM patients with/without malignancy. The presence of underlying malignancy did not affect hospitalization cost, length of stay, or mortality in the hospitalized DM population. The economic burden of hospitalized DM patients is increasing over time.
conclusionsDM inpatients with malignancy display numerous differences compared to DM inpatients without malignancy. Further research characterizing hospitalized DM patients is warranted in order to optimize work-up and treatment guidelines for these patients.
