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

objectiveThis study aimed to promote an understanding of spontaneous pneumothorax by analysing the prevalence rate and medical service use by patients with spontaneous pneumothorax according to sociodemographic characteristics.

designA 12-year nationwide study.

settingData obtained from the Korean National Health Insurance Service Sharing Service.

participantsA total of 4658 participants who used medical services due to spontaneous pneumothorax between 2002 and 2013 in Korea. OUTCOME MEASURES: For those diagnosed with spontaneous pneumothorax, use of medical services, hospitalisation data, sociodemographics, comorbidity, treatment administered and medication prescribed were recorded.

resultsThe annual prevalence of spontaneous pneumothorax ranged from 39 to 66 per 100 000 individuals, while the prevalence of hospitalisation due to spontaneous pneumothorax ranged from 18 to 36 per 100 000 individuals. The prevalence rate of spontaneous pneumothorax in Korea has increased since 2002. The male to female ratio was approximately 4-10:1, with a higher prevalence rate in men. By age, the 15-34 years old group, and particularly those aged 15-19 years old, showed the highest prevalence rate; the rate then declined before increasing again for those aged 65 years or older. In total, 47%-57% of patients with spontaneous pneumothorax underwent hospitalisation. The average number of rehospitalisations due to pneumothorax was 1.56 per person, and more than 70% of recurrences occurred within 1 year. Chronic obstructive pulmonary disease was the most common comorbidity. The average treatment period was 11 days as an outpatient and 14 days in-hospital. The average medical costs were $94.50 for outpatients and $2523 for hospital admissions. The most common treatment for spontaneous pneumothorax was oxygen inhalation and thoracostomy, and the most commonly prescribed medications were analgesics, antitussives and antibiotics.

conclusionsWe here detailed the epidemiology and treatments for spontaneous pneumothorax in Korea. This information can contribute to the understanding of spontaneous pneumothorax.
