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
Introduction: The interaction between attention and emotion is one of the key questions in schizophrenia, but the mechanisms of how emotional information affects selective attention in schizophrenia are still unclear. Methods: The present study employed a cue-back-to-fixation procedure to manipulate the valence and emotional arousal intensity of stimuli presented at either cued locations (Experiment 1) or target locations (Experiment 2). The present study examined the impact of emotional arousal intensity on the inhibition of return (IOR)-a phenomenon characterized by faster responses to previously unattended relative to attended locations-in individuals with schizophrenia, during two distinct attentional phases: attentional disengagement and attentional reorientation. Results: The results showed significant IOR effects for both schizophrenia (Experiment 1a and 2a) and control groups (Experiment 1b and 2b) regardless of the emotional stimuli with different arousal intensities presented at both the cued and target locations. However, as compared with negative low arousal stimuli or neutral low arousal stimuli, significantly larger IOR effect size for control groups was found when negative high arousal stimuli were presented in cued location and for schizophrenia groups was found when negative high arousal stimuli were presented in target location. Discussion: These results may underly the mechanism of attentional deficit for schizophrenia towards different arousal intensities of emotional stimuli. During the attentional disengagement phase, schizophrenia patients are more likely to filtered out those high-arousal stimuli that endanger life while control group participants experience enhanced perceptual processing towards them; during the attentional reorientation phase, schizophrenia patients display "hyperfocusing" on those life-threatening high-arousal stimuli while the control group manifest an "attentional blindness" phenomenon to avoid these threatening stimuli. Meanwhile, we also interpreted our findings in light of an alternative theory of salience dysregulation.
