The human brain modulates sniffs according to fine-grained perceptual features of odours.

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
Sensorimotor feedback is a fundamental mechanism of active sensing. In olfaction, the primary motor behaviour is the sniff. Thus, in active olfactory sensing, we would expect the dynamics of the sniff to change according to detailed odour characteristics. Furthermore, percept-related modulations of sniffing behaviour should correspond to neural activity in participating brain regions. Here we analysed a high-precision functional MRI dataset including more than 4,300 sniffs per participant taken of 160 odours during ~18 hours of scanning, to probe the relationship between odour-induced sniff modulations and perceptual features at a high level of granularity. We found that fine-grained perceptual odour information-and even odour identity-can be decoded from sniffing dynamics, and that olfactory brain regions, particularly the amygdala, are involved in percept-driven modulation of sniffing behaviour. Thus, olfactory cortical areas participate in real-time modulations of sniffs according to perceptual properties of the odour at a high level of granularity.
