Time-of-day variation in motivation for everyday behaviors: A cluster-based approach to understanding individual differences.
Article in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Motivation governs everyday behavior and is often disrupted in psychiatric conditions, yet how motivation varies within the day, and how these patterns differ between individuals remains unclear. Here, we examined diurnal patterns of momentary subjective motivation for everyday activities, their translation into behavior, and how these patterns vary by trait-based measures linked to motivation. At baseline, 538 participants (424 women, 112 men, 2 non-binary, aged 18-77 years) completed questionnaires indexing psychiatric traits associated with altered motivation, revealing four clusters differing in appetitive motivation, and depressive features with varying levels of goal-directed behavior.
