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

aimsSleep difficulties among adolescents are of a significant concern given its associations with adverse health outcomes. The aims of the present study were to examine trends and predictors of self-perceived difficulties in getting to sleep among adolescents in the Nordic countries.

methodsThe study was based on cross-sectional data from 10- to 17- year-olds (

resultsSince 2002, the prevalence of self-perceived difficulties in getting to sleep has risen in all Nordic countries. However, from 2014 to 2018, the trend of adolescents reporting difficulty more than weekly increased in Denmark, Finland, Greenland, and Norway, whereas it was mostly stable in Sweden, and Iceland showed a reduction. Predictors of difficulties in getting to sleep varied across countries, but younger age, reduced life satisfaction, decreased physical activity, feeling low, and feeling nervous were common predictors across the six countries. Gender and perceived family wealth had different effects on difficulties getting to sleep in different countries.

conclusionsPrevalence of and trends in difficulties getting to sleep varied by country, with a concerning rise identified in Greenland, 2006-2018. Predictors such as feeling low, feeling nervous, age, gender, life satisfaction, physical activity, and perceived family wealth varied by country and thus emphasize the need for tailored interventions to address diverse challenges in adolescent sleep health.
