Healthcare Service Use Patterns Among Patients with Acid Sphingomyelinase Deficiency Type B: A Retrospective US Claims Analysis.
Article in Advances in therapy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionAcid sphingomyelinase deficiency (ASMD) is a rare lysosomal storage disease. Patients with ASMD type B experience multiple morbidities, potentially leading to early mortality. Before the 2022 approval of olipudase alfa for non-neuronopathic ASMD manifestations, only symptom management was offered. Data on healthcare services used by patients with ASMD type B are limited. This analysis used medical claims data to evaluate real-world healthcare service use by patients with ASMD type B in the United States of America (USA).
methodsThe IQVIA Open Claims patient-level database (2010-2019) was cross-examined. Two patient cohorts were identified: the primary analysis cohort, which included patients with at least two claims associated with ASMD type B (ICD-10 code E75.241) and more total claims with ASMD type B than any other ASMD types, and the sensitivity analysis cohort, which included patients with a high probability of having ASMD type B identified using a validated machine-learning algorithm. Claims for ASMD-associated healthcare services were recorded, including outpatient visits, emergency department (ED) visits, and inpatient hospitalizations.
resultsThe primary analysis cohort included 47 patients; a further 59 patients made up the sensitivity analysis cohort. Patient characteristics and healthcare service use were similar in both cohorts and were consistent with established characteristics of ASMD type B. Overall, 70% of the primary analysis cohort from this study were aged < 18 years, and the liver, spleen, and lungs were the most frequently affected organs. Cognitive, developmental, and/or emotional problems and respiratory/lung disorders caused most outpatient visits; respiratory/lung disorders accounted for most ED visits and hospitalizations.
conclusionThis retrospective analysis of medical claims data identified patients with ASMD type B who had characteristics typical of this condition. A machine-learning algorithm detected further cases with a high probability of having ASMD type B. High use of ASMD-related healthcare services and medications was observed in both cohorts.
