Incidence and prevalence of Spinal and bulbar muscular atrophy in South Korea: a nationwide population-based study.
Article in Journal of neurology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 2 of them syntheses 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
Spinal and bulbar muscular atrophy (SBMA), or Kennedy's disease, is a rare X-linked neuromuscular disorder predominantly affecting males and caused by a mutation in the androgen receptor gene. The epidemiology and comorbidities associated with SBMA in different ethnicities remain poorly understood. This study investigated the prevalence, incidence, and comorbidities associated with SBMA in the South Korean population using the Health Insurance Review and Assessment Service (HIRA) database. We retrospectively reviewed diagnosed cases of SBMA (G12.25 code of the Korean Classification of Diseases-7th edition) registered from January 1, 2016, to December 31, 2019, to calculate incidence and prevalence rates and concomitant comorbidities. Additionally, we surveyed SBMA patients (questionnaire group) visiting our clinic in 2022 to compare comorbidities with the HIRA data. The mean incidence rate of SBMA in the Korean population was 0.36/100,000 males from 2018 to 2019, while the prevalence rate was approximately 0.46/100,000 males from 2016 to 2019. The most common comorbidities identified in HIRA were gastritis and duodenitis (99.7%), gastroesophageal reflux (90.5%), hyperlipidemia (88.4%), and liver disorders (75.2%), which showed similar results in the questionnaire group. Additionally, gastric cancer was the most common type of cancer reported in SBMA in South Korea; although indeterminate, age-related factors may contribute to the development of cancer in these patients. Our findings provide valuable insights into the epidemiology and associated comorbidities of SBMA within the Korean population, which could inform clinical practice and future clinical research.
