Trial report in BMJ (Clinical research ed.), 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01070251 (Effects of a Multimodal Preference-based Parental Intervention on Preschoolers' Physical Activity Behaviour - a Cluster-randomized Trial), which is not on this map. Cited by 122 papers, 26 of them syntheses that pooled it.

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.

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.

Abstract

objectiveTo assess whether a physical activity intervention reduces body mass index in young children.

designCluster randomised controlled single blinded trial over 12 months.

settingThirty six nurseries in Glasgow, Scotland.

participants545 children in their preschool year, mean age 4.2 years (SD 0.2) at baseline.

interventionEnhanced physical activity programme in nursery (three 30 minute sessions a week over 24 weeks) plus home based health education aimed at increasing physical activity through play and reducing sedentary behaviour.

main outcome measureBody mass index, expressed as a standard deviation score relative to UK 1990 reference data. Secondary measures were objectively measured physical activity and sedentary behaviour; fundamental movement skills; and evaluation of the process.

resultsGroup allocation had no significant effect on the primary outcome measure at six and 12 months or on measures of physical activity and sedentary behaviour by accelerometry. Children in the intervention group had significantly higher performance in movement skills tests than control children at six month follow-up (P=0.0027; 95% confidence interval 0.3 to 1.3) after adjustment for sex and baseline performance.

conclusionsPhysical activity can significantly improve motor skills but did not reduce body mass index in young children in this trial.
