Multidimensional assessment of self-reported chemical intolerance and its impact on chemosensory effects during ammonia exposure.

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
purposeHealthy individuals differ in self-reported chemical intolerance (CI). It is unclear whether this inter-individual variability impacts well-being and performance in environmental and occupational settings with chemical exposures. So far, operational definitions and questionnaires of CI have either emphasized physical symptoms or affective/behavioral disruption. In contrast, this study focused on healthy individuals who reported strong CI which generalized to awareness, physiology, affect, and behavior. We investigated whether generalized self-reported CI is associated with hyper-reactivity and reduced cognitive functioning due to chemosensory-mediated distraction during ammonia exposure.
methodsAn online sample (N = 321) answered established CI questionnaires. Based on the convergent self-reports in these questionnaires, healthy women with generalized CI and healthy female control participants were selected (total N = 26). Baseline characterization was performed using implicit association, lung and olfactory function tests, health-related self-reports, plasma inflammatory and metabolic markers. Performance in neurobehavioral tasks, perceptual ratings, nasal inflammatory, neuroendocrine, and autonomic nervous system reactivity were examined by means of a 75-min whole-body challenge to ammonia (stepwise increase: 0-10 ppm).
resultsCorrelational analyses confirmed the multidimensionality of CI. Participants with generalized self-reported CI exhibited better olfactory function and reported stronger pungency during the challenge than controls. Cognitive performance and physiological response to the challenge were comparable between the two groups.
conclusionsSelf-reports of CI are complex and not easily assessed by unidimensional questionnaires. While generalized self-reported CI is associated with altered chemosensory processing, it seems unlikely that it modulates health effects and cognitive functioning during chemical exposure.
