The effects of sleep restriction and time of day on food-specific impulsivity, approach-avoidance bias and delay discounting.

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
Background: Insufficient sleep and circadian timing are both linked with obesity, primarily via unhealthy food choice, yet the cognitive mechanisms underpinning such relationships remain unclear. Methods: Across two studies, we implemented an ecologically valid within-subjects at-home protocol. Study 1 ( Results: During the night, participants indicated steeper discounting rates relative to the afternoon. Furthermore, such rates predicted higher liking of high-calorie food choices regardless of time of day and when sleep restricted. Approach bias for low-calorie food interacted with the night condition in predicting both low- and high-calorie food choices. Conclusion: Both delay discounting and approach bias may be important cognitive mechanisms predicting food liking and choice under sleep restricted and altered circadian timing conditions. Further research should replicate such results using real rewards.
