Cognitively engaging sedentary activities are associated with better cognitive function in middle-aged adults: a cross-sectional study using the 1970 British Cohort Study.

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
backgroundPrior research examining sedentary time and cognitive function has produced mixed findings with limited attention to specific types of sedentary behavior. This cross-sectional study tested the hypothesis that more cognitively active sedentary behaviors (playing video games, internet use, and reading) are positively associated with cognitive performance, in contrast to cognitively passive sedentary behavior (watching television).
methodsData from 3,943 participants (aged 46-48; 53.3% female) with valid activPAL3 accelerometry, self-reported time spent doing sedentary behaviors, cognitive assessment scores (10-word auditory verbal learning test, category verbal fluency [animal naming] and two-letter cancellation task), and covariate data (sex assigned at birth, moderate-to-vigorous intensity physical activity [MVPA], occupational physical activity, and level of education) were cross-sectionally analyzed from the Age 46 Biomedical Sweep of the 1970 British Cohort Study. Linear regression models, including sex-stratification, evaluated associations between device-measured activity monitoring and specific sedentary behaviors with standardized cognitive assessment scores (z-scores) and a composite global cognition score (primary outcome).
resultsIn adjusted pooled models, MVPA was positively associated with better global cognition (β = 0.069 ± 0.021 [0.027-0.110] per hour/day, p
conclusionWhile the cognitively passive sedentary behavior of watching television was not associated with global cognition, the more cognitively active sedentary behaviors of reading and internet use were associated with better global cognition in middle-aged adults. These cross-sectional findings highlight potential concurrent behavioral targets for cognitive health in middle-aged adults. The data suggest that lifestyle strategies might optimize cognitive outcomes by prioritizing the accumulation of MVPA, while concurrently supporting a more cognitively active composition of unavoidable sedentary time.
