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

Introduction: Loneliness in older adults is recognized as a psychosocial factor influencing cognitive performance. This study examines the impact of self-perceived loneliness both on actual cognitive performance and on individuals' self- perceived cognitive abilities. Methods: A sample of 510 healthy older adults (354 females) aged between 64 and 103 years (mean = 78.78±8.72) was studied. Participants' self-perceived loneliness was assessed on UCLA Loneliness Scale-3 (Hughes et al., 2004), their cognitive performance with the standardized cognitive screening GEMS (Global Examination of Mental State) and their self-perceived cognitive efficiency with SMAC (Sclerosi Multipla Autovalutazione Cognitiva [Multiple Sclerosis cognitive self-evaluation]). Results: Results showed that the higher the perceived loneliness, the worse the cognitive performance (B = -1.18; Discussion: Loneliness in older adults should be regarded as highly impactful not only on cognitive performance but also on perception of one's own abilities. Indeed, even when cognitive efficiency is well preserved, loneliness leads to underestimation of personal cognitive resources.
