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

Research shows that schools can make a positive impact on children's nutritional outcomes. However, it is also reported that schools and teaching staff note many barriers, which may restrict nutritional education programming and delivery. This is concerning, considering the view that teachers are the key agents for promoting health and nutrition within schools. The purpose of the updated systematic review and meta-analysis was to ascertain the impact that nutrition education programs have on elementary-aged students' energy intake, fruit, vegetable, sugar consumption and nutritional knowledge. A systematic literature search was conducted using electronic databases (The Cochrane Central Register of Controlled Trials (CENTRAL); A + Education; ERIC; PsycINFO; MEDLINE; ProQuest Central, Journals@Ovid and SAGE Health Sciences Full-Text Collection) from 1990 to 31st October 2018. This process yielded 34 studies for inclusion in this systematic review and meta-analysis. Of these studies, seven studies had a focus on energy intake, five had a focus on sugar consumption, 21 of the studies looked at fruit and vegetable consumption and 13 studies focused on nutritional knowledge. The results suggest that the teaching of nutrition education in elementary schools by qualified teachers can make an important contribution to the knowledge and dietary habits of children. The small and medium effect sizes indicate that prudent, evidence-based decisions need to be made by policy makers and pedagogues as to the teaching strategies employed when delivering nutrition education programs to elementary-aged students. The review is reported in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (van Sluijs et al., 2007).
