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

backgroundThe assessment of theory of mind (ToM) performance in Alzheimer's disease (AD) and amnestic mild cognitive impairment (aMCI) remains inconclusive. We conducted a meta-analysis to investigate ToM performance in patients with aMCI and AD.

methodsA systematic literature search was performed for eligible studies published up to July 2019 in three international databases (PubMed, Embase, and Web of Science). Due to heterogeneity between studies, a random-effects model was used. Individual ToM tasks were meta-analyzed separately and possible sources of heterogeneity were examined.

resultsIn total, 36 studies involving 701 individuals with AD and 197 with aMCI were identified. Compared with healthy controls, ToM was impaired in both AD (d = 1.45) and aMCI patients (d = 0.65). In AD patients, ToM was particularly impaired in advanced tasks such as Faux Pas Recognition (d = 1.26). In patients with aMCI, ToM deficits were relatively modest, with the exception of the reading the mind in the eyes task (d = 1.22). ToM was significantly more impaired in AD than that in aMCI (d = 0.88).

conclusionsThis is the first meta-analysis examining ToM performance in AD and aMCI simultaneously. The results showed that ToM deficits were more severe in AD than that in aMCI in most individual ToM tasks. Longitudinal studies are warranted to determine whether ToM abilities in aMCI patients can be used for prognostic purposes.
