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

backgroundRecent data suggest that individuals with intellectual disability and borderline intellectual functioning are at greater risk of experiencing loneliness compared to the general population. This review aimed to explore how loneliness is perceived among these groups and to identify possible factors associated with it.

methodA systematic review was performed following PRISMA guidelines, covering four databases. The methodological quality of the included studies was assessed using a standardized assessment tool.

resultsForty studies met the inclusion criteria, yielding a sample-size-weighted mean of loneliness of 41.70% in individuals with intellectual disability; evidence for borderline intellectual functioning was limited to one study (24.20%). Loneliness was associated with factors at the individual, social, and structural levels.

conclusionsLoneliness is a prevalent issue among individuals with intellectual disabilities and borderline intellectual functioning. Further research is required to examine more thoroughly the associated factors and guide the development of effective interventions.
