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

Subjective cognitive decline (SCD) may constitute an early marker of mild cognitive impairment (MCI) in individuals with isolated REM sleep behavior disorder (iRBD). In this cross-sectional study, 80 individuals with iRBD were classified into iRBD with MCI (RBD.MCI), with SCD (RBD.SCD+), and without both (RBD.SCD-) based on neuropsychological testing and the Multi-SubCoDE questionnaire. The prevalence of SCD in iRBD was 36.3%, with predominance of the amnestic multi-domain SCD profile. RBD.SCD+ reported more severe depressive symptoms than RBD.SCD- and showed lower cognitive performance than RBD.SCD- in global cognition and attention & working memory. Magnetic resonance imaging analyses revealed lower grey matter volume in the left superior frontal gyrus for RBD.SCD+ than RBD.SCD-, which was associated with increased SCD-severity and lower global cognition. SCD without MCI in iRBD is associated with subtle cognitive deficits and structural brain changes. The prognostic value of SCD in iRBD should be further determined in longitudinal studies.
