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

introductionSocial cognition (SC) is often impaired by dementia, contributing to difficulties with relationships and social isolation. Additionally, people with dementia frequently have impaired awareness of their impairments, which may worsen distress for them, their family, and friends. We investigated SC in people with Alzheimer's disease (PwAD), awareness of SC, and whether PwAD overestimate SC abilities compared to healthy controls (HC).

methodsParticipants completed the Interpersonal Reactivity Index perspective-taking subscale (IRI-PT), a self-report measure of SC, and The Awareness of Social Inference Test (short form) (TASIT-S), a task-based measure of SC. Insight was evaluated by comparing self-assessment with TASIT-S performance. The Addenbrooke's Cognitive Examination (version 3; ACE-III) measured general cognition.

resultsWe recruited 70 PwAD (mean age = 78.13; mean ACE-III = 71.80) and 17 HC (mean age = 71.53; mean ACE-III = 96.65). PwAD self-reported lower theory of mind (ToM) (IRI-PT = -2.16, 95% CI = -0.33 to 4.64, p = 0.09) and performed worse on TASIT-S emotion recognition (-2.04, 95% CI = -2.89 to -1.20, p < 0.001), sarcasm recognition (-0.91, 95% CI = -1.66 to -0.16, p = 0.02), and ToM assessments (-1.42, 95% CI = -2.27 to -0.57, p = 0.001). There was no significant relationship between IRI-PT and TASIT-S ToM in either group, nor in the participant group as a whole. We categorised "under-estimators" (low IRI-PT, high TASIT-S ToM), "over-estimators" (high IRI-PT, low TASIT-S ToM), and "congruent-estimators" and found that lower ACE-III was associated with ToM over-estimation.

conclusionDifferences in self-reported and task-assessed SC were observed between PwAD and HC, but self-estimated and task-assessed ToM were not associated, suggesting that SC self-estimation is unreliable in PwAD and possibly in healthy older adults.
