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

objectiveTo develop a dietary questionnaire on food habits, eating behaviour and nutrition knowledge of adolescents and to examine its reliability.

designA cross-sectional baseline survey. The questionnaire was self-administered to study participants twice with 7 days between each administration.

settingA school community in Pavia, Italy. SUBJECTS: A group of students (n=72, aged 14-17 y, both sexes) studying in a secondary school in the second year of the course were invited to compile a dietary questionnaire during school time. Informed written consent was obtained from each subject and their parents. Subjects were initially recruited for a nutrition intervention; recruitment was opportunistic and school based. STATISTICAL ANALYSES: Reliability was assessed using the Cronbach's alpha and the Pearson correlation coefficients.

resultsCronbach's alpha ranges from a minimum of 0.55 to a maximum of 0.75, indicating that only two sections have a poor internal consistency. The Pearson correlation coefficients range from a minimum of 0.78 to a maximum of 0.88, indicating a very good temporal stability of the questionnaire. All the Pearson correlation coefficients are statistically significant with P<0.01.

conclusionsThe present questionnaire has the potential to measure the effects of nutrition interventions on adolescents because of its stability in making comparisons over time. The instruments is low in cost and easy to administer and analyse; moreover, it could be modified appropriately to fit the needs of other populations as well.
