A Comparative Analysis of Eye Movement Accuracy for Locating Items Held in Visual Short-Term Memory Among Young Healthy Adults, Older Adults With Normal Cognition, and Older Adults Indicative of Mild Cognitive Impairment.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundWe compared the accuracy of eye movements in locating an item stored in visual short-term memory between young healthy adults, normally aging older adults, and older adults with mild cognitive impairment as indicated by the Montreal Cognitive Assessment or Addenbrooke's Cognitive Examination-III test.
methodsThirty-three young healthy adults, 38 normally aging older adults, and 17 older adults indicative of MCI completed two experiments requiring object-location binding. In Experiment 1, participants viewed 2-4 memory items displayed sequentially at random screen locations. Following a 900 ms interval, eye movements were recorded while participants moved their eyes to the location of the memory item corresponding to a displayed cue. In Experiment 2 (control), participants indicated whether or not the test item was shown at its original location using a yes/no response.
resultsMCI-indicative participants exhibited greater saccadic error (spatial deviation of saccadic endpoint from the remembered target location) than normally aging older (p = 0.002) and young (p < 0.001) participants at low memory load only. At higher memory load, the saccadic error distance was greater for all groups (p < 0.001). Moreover, in Experiment 2, MCI-indicative participants exhibited significantly poorer memory performance than normally aging older adults, but only at lower memory load (p = 0.02).
conclusionSaccadic accuracy declined with memory load for all groups. The MCI-indicative group showed lower saccadic accuracy versus normally aging older and young adults at low memory load. The findings offer important insights into our understanding of saccadic eye movement as a potential behavioral marker for MCI.
