1 · What the graph read from it

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.

2 · The registry

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

backgroundResearch based on embodied cognition has demonstrated that physical posture, particularly an upright seated posture, can influence emotions and cognition. However, although students spend most of the day sitting in classrooms, intervention research on upright seated postures suitable for learning environments is limited.

aimsWe aimed to examine the effects of postural intervention via a 'Zazen-like upright-support seating furniture' (a risshin chair) on physical posture, class time perception, positive affect, and daily sense of fulfilment in school in a junior high school setting. SAMPLE: The participants were 48 second-year junior high school students (25 girls and 23 boys; M

methodsUsing a within-participants design, students alternated between sitting in regular and risshin chairs in an A-B-A-B-A order for approximately five weeks. At the end of each week, they completed a self-report questionnaire during the final homeroom session on every Friday.

resultsBayesian linear mixed-effects modelling revealed significant effects of the risshin chair on posture-related outcomes, such as autonomous posture improvement, straight back, and tension release. Bayesian mediation analysis with linear mixed-effects modelling further showed that the risshin chair reduced time-related distracted thoughts, increased pleasantness, and enhanced daily school fulfilment, with these effects mediated via improved straight-back posture.

conclusionsAlthough short-term, the risshin chair improved specific aspects of students' physical posture, class time perception, and subjective well-being during school compared with regular chairs.
