1 · What the graph read from 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.

2 · The registry

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

objectiveStudies of dermatomyositis (DM) are frequently limited to single-centre cohorts. We used two large nationally representative US cohorts to conduct a descriptive epidemiological study of the characteristics, treatments and outcomes of patients with incident DM.

methodsThis retrospective study identified two DM inception cohorts using (1) commercial claims and (2) electronic health record (EHR) data from the Excellence Network in Rheumatology to Innovate Care and High-impact research (ENRICH), a community rheumatology practice-based research network. Patient characteristics, treatments and healthcare utilisation were assessed using the 18 months before and 12 months after diagnosis in claims and the 12 months before and after diagnosis in EHR data.

resultsWe identified 2475 patients (claims) and 1196 patients (EHR) with incident DM. Among 998 patients in the EHR cohort with available laboratory data, 472 had available myositis panel results, with 165 (35.0%) having a positive myositis-specific antibody. Glucocorticoid use was common, 68.7% and 73.8% in the two cohorts, respectively, with initial doses most often >20 mg/day; among glucocorticoid users, mean cumulative dose was 1407 mg in the claims cohort. Hydroxychloroquine, methotrexate and mycophenolate were the most commonly used immunomodulatory therapies. During follow-up in the claims data cohort, incidence per 1000 person-years was 92.2, 15.3, 6.4, 2.9 and 2.1 for all-cause hospitalisation, malignancy, interstitial lung disease, gastrostomy tube placement and myocarditis, respectively.

conclusionAdministrative claims and EHR data can be leveraged to assess treatment patterns and longitudinal outcomes/disease manifestations in incident dermatomyositis cohorts. This study highlights a high burden of glucocorticoid exposure, significant heterogeneity in treatment and high healthcare utilisation in this population.
