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

introductionAcross two studies, we investigated whether global eye movement similarity reflects visuospatial memory impairment in older adults, aiming to identify a novel neuropsychological marker of mild cognitive impairment (MCI).

methodsIn Study 1, 35 participants completed a global eye movement similarity memory (GEMS-M) task, viewing indoor scene images with three objects and identifying changes during the recognition phase. In Study 2, 60 participants (30 healthy controls, 30 with MCI) completed a passive version of the task without explicit memory judgment.

resultsStudy 1 showed that the similarity of global eye movement patterns between encoding and recognition phases predicted memory performance, particularly when an object was added. Study 2 demonstrated that global eye movement similarity, combined with demographics, discriminated MCI patients from healthy controls with an AUC of 0.93. DISCUSSION: Our findings suggest that global eye movement similarity may serve as a promising tool for the early detection of MCI.
