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
backgroundCognitive decline is a major public health concern in aging societies, and physical activity (PA) is a key modifiable factor. Some individuals concentrate their PA into one or two days per week-the "weekend warrior" pattern-but its long-term relationship with cognitive changes remains unclear. This study aimed to examined the association between the weekend warrior pattern and cognitive trajectories among middle-aged and older adults in China.
methodsData were derived from the China Health and Retirement Longitudinal Study (CHARLS, 2013-2018). A total of 1,530 adults aged ≥ 45 years who completed three survey waves were included. Group-based trajectory modeling (GBTM) was used to identify distinct cognitive trajectories, and multinomial logistic regression with hierarchical adjustment assessed associations between the weekend warrior pattern and these trajectories.
resultsSix distinct cognitive trajectories were identified. Compared with the Cognitive Impairment-Persistent Low group, participants adopting the weekend warrior pattern were significantly more likely to belong to the Cognitive Normal-Stable group (Model5: OR = 2.685, 95% CI: 2.68-2.69, P < 0.001). Sensitivity and subgroup analyses yielded consistent results, supporting the robustness of the association.
conclusionThe weekend warrior PA pattern was significantly associated with more favorable cognitive trajectories among middle-aged and older adults. Concentrating PA within one or two days per week may offer long-term cognitive benefits and represents a practical strategy for promoting brain health in aging populations.
