The associations of different recess types on physical activity and sedentary behaviour in Estonian primary school students.
Article in European journal of public health, 2025. 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
Students' physical activity (PA) levels tend to decrease with increasing age; however, the school day structure can potentially influence students' PA levels. This study aimed to measure and compare objective levels of PA during recess and school time between schools with different recess types. 15 different schools were selected, and accelerometry-based PA levels of 9-13-year-old students were measured. Schools were selected based on the recess types: (i) 'daily outdoor recess'; (ii) 'irregular outdoor recess'; (iii) 'indoor recess'. The 'daily outdoor recess' group reached the highest moderate-to-vigorous PA (MVPA) during recess compared to other groups. 'Indoor recess' group had more sedentary time during recess compared to 'irregular outdoor recess' and 'daily outdoor recess' groups (43.6 ± 1.0%, 34.0 ± 1.0%, 30.8 ± 0.8%, respectively; P < .05). Time in MVPA was unchanged during recess across all grades in the 'daily outdoor recess' group (from 22.8% to 25.6%), while decreased MVPA from 27% to 17% and from 21% to 10% was found in 'irregular outdoor recess' and 'indoor recess' group, respectively; P < .05. Sedentary time increased from 34% to 52% in the 'indoor recess' group and from 26% to 43% in the 'irregular outdoor recess' group (P < .05). There was a positive association between the recess length and MVPA minutes acquired during recess; however, during a 15-25 min outdoor recess, students spent more time in MVPA compared to a 30-50 min outdoor recess (28%-30.5%, 21%-23%, respectively). The findings emphasize that unstructured outdoor recess has a high potential to maintain the MVPA levels with increasing age.
