Pupillary responses to differences in luminance, color and set size.
Article in Experimental brain research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
The pupil responds to a salient stimulus appearing in the environment, in addition to its modulation by global luminance. These pupillary responses can be evoked by visual or auditory stimuli, scaled with stimulus salience, and enhanced by multisensory presentation. In addition, pupil size is modulated by various visual stimulus attributes, such as color, area, and motion. However, research that concurrently examines the influence of different factors on pupillary responses is limited. To explore how presentation of multiple visual stimuli influences human pupillary responses, we presented arrays of visual stimuli and systematically varied their luminance, color, and set size. Saliency level, computed by the saliency model, systematically changed with set size across all conditions, with higher saliency levels in larger set sizes. Pupillary constriction responses were evoked by the appearance of visual stimuli, with larger pupillary responses observed in larger set size. These effects were pronounced even though the global luminance level was unchanged using isoluminant chromatic stimuli. Furthermore, larger pupillary constriction responses were obtained in the blue, compared to other color conditions. Together, we argue that both cortical and subcortical areas contribute to the observed pupillary constriction modulated by set size and color.
