Visual-Spatial Search in Neglect Syndrome as a Function of the Number of Stimuli in the Hemifields.
Article in Healthcare (Basel, Switzerland), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundNeglect syndrome is a serious condition that often affects the ability to perform visual-spatial search tasks, interfering with the ability to detect stimuli on the left side of space. A number of factors can affect the success of visual search in patients with neglect syndrome, including visual field load. The purpose of this study is to investigate how the number of stimuli in the right visual hemifield influences the efficiency of visual search in the left (neglected) hemifield, hypothesizing that an increased object load on the right side may impair search performance on the left.
methodsThe sample comprised 30 patients with neglect syndrome as the target group and 20 patients with right hemisphere damage but no signs of hemispatial neglect as the control group. This study employed several neuropsychological tests, including neuropsychological examination according to the scheme of A.R. Luria. The SPSS 23.0 software was used for statistical analysis of the data.
resultsThe Red Shapes test revealed a significant decrease in the number of stimuli detected in both the right and left visual hemifields across successive series (
conclusionsThis study confirmed that the number of elements in the right visual hemifield influences the ability to detect elements in the left hemifield in patients with left-sided neglect, as demonstrated using the Red Shapes test.
