Increasing Numbers of Persons with Sleeping Problems in Sweden.

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
objectivesThis study investigated sleeping problems in the Swedish population based on the Swedish National Board of Health and Welfare's national patient register on numbers of patients in specialized outpatient care diagnosed with codes for sleeping problems.
methodsNumbers of patients per year and per 100,000 inhabitants in various age groups: 0-4, 5-19, 20-39, 40-59, and 60+ years diagnosed each year between 2001 and 2024 with the ICD codes G47 (sleep disorders) or F51 (non-organic sleep disorders) as main diagnosis were assessed.
resultsThe highest increase for sleep disorders was seen among children, adolescents, and young adults. All results are given per 100,000 persons. In the age group 0-4 years, the numbers of sleep disorders (G47) increased from 41.5 in 2001 to 215.8 in 2024. The corresponding results in the age group 5-19 years were 13.8 and 235.6, respectively. In the age group 20-39 years, 40.4 were diagnosed in 2001 and 220.9 in 2024. For subjects aged 40-59 years, 169.5 were diagnosed in 2001 and 362.8 in 2024, and for persons aged 60+ years, 116.4 were diagnosed in 2001 and 322.9 in 2024. No major changes in the numbers of persons with F51, non-organic sleep disorders, were observed.
conclusionsSleeping problems can be caused by several factors; however, the rapid increase in recent years has temporally coincided with an increase in the public's exposure to microwave radiofrequency (RF) radiation and increasing use of screens. RF radiation and use of screens may negatively impact sleep.
