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

objectivesTo describe the epidemiology, patient characteristics and comorbidities in patients with Wilson disease (WD) in the USA.

designRetrospective, population-based study.

settingThe study used the US Komodo claims database containing records regarding medical claims for over 120 million individuals.

participantsPatients with WD were identified via ICD-10 (10th revision of the International Classification of Diseases) code during the study period 2016-2019 and no age restriction was applied. A further stratification by disease subtype ('hepatic', 'neurologic' and 'psychiatric') was performed.

main outcome measuresWD prevalence was reported by age, sex and US census regions/divisions. Adjusted prevalence was calculated using age-specific prevalence standardised to the USA (2010 US census) and to the world (WHO 2000-2025) to enable comparisons across countries, using direct standardisation of prevalence estimates by age group.

resultsOverall, 2115 patients with WD were identified during the study period. Among them, 56.8% had hepatic symptoms, 57.0% neurologic symptoms and 47.4% psychiatric symptoms. The most frequent manifestations in hepatic patients were liver signs and symptoms (90.8%), in neurologic patients cognitive defects (50.7%) and in psychiatric patients mood disorders (86.4%). The mean age in the overall cohort was 39.9 years. Prevalence estimation was based on 1481 patients with WD between 2017 and 2019. The 2017-2019 crude period prevalence was 21.2 patients per million (95% CI: 20.1 to 22.3), with similar prevalence observed for both sexes.

conclusionsThis study provides important real-world data on the diagnosed prevalence of WD in the USA and revealed the comorbidities associated with various disease subtypes, thereby providing a comprehensive basis for guiding physicians and policy makers in the management of this chronic disease.
