The Daily Mile and children's physical activity, mental health and educational performance: a quasi-experimental study in Greater London primary schools.

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
Objectives: To examine associations between The Daily Mile, a school-based active mile intervention, and pupils' physical activity, mental health and educational performance. Methods: Year 1 pupils (aged 5-6 years) from Greater London primary schools were invited. Schools were allocated to The Daily Mile or non-Daily Mile group based on their reported Daily Mile participation. We measured weekday school hours mean minutes of moderate-to-vigorous physical activity (MVPA) using GENEActiv accelerometers. Other outcomes included time spent sedentary and in light activity, mental health and educational performance. Multi-level linear regression models examined differences accounting for repeated measurements (day) clustered by pupils-, class- and school-level, with adjustments for sex, ethnic group, area-level deprivation and month of assessment. Results: A total of 1004 pupils/40 schools were recruited and assessed between October 2021 and January 2023; 21 schools/499 pupils comprised The Daily Mile group; 19 schools/505 pupils the non-Daily Mile group. Daily Mile pupils spent 2.2 min more in MVPA compared with non-Daily Mile pupils, but the difference was not significant (0.78, 95% CI -2.14 to 3.69). Daily Mile pupils spent less time sedentary and more time in light activity compared with the non-Daily Mile pupils, but not significantly (-5.06, 95% CI -15.37 to 5.26 and 3.27, 95% CI -4.26 to 10.81, respectively). There were no differences in mental health or educational performance. Conclusions: We found no associations between The Daily Mile and pupils' physical activity, mental health and educational performance. Pupils in our study were in year 1 with early exposure to the intervention; assessments over longer periods are needed to understand any benefits.
