Snack cost and percentage of body fat in Chinese children and adolescents: a longitudinal study.
Article in European journal of nutrition, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeOnly a few studies examined the relationship between snack cost and change in the percentage of body fat in children. We thus conducted a longitudinal study to investigate whether high snack cost is associated with fast increase in the percentage of body fat in Chinese children.
methodsThe study included 2368 children (1126 girls and 1242 boys, aged 6-14 years). Percentage of body fat was repeatedly assessed by bioelectrical impedance analysis in 2014 (baseline), 2015 and 2016. Snack cost in 2014 was estimated by self-report associated with purchasing snacks at school and classified into low, moderate, and high group. Association between snack cost and repeated percentage of body fat was analyzed with linear mixed models, adjusting for demographic factors, diet, physical activity, and parental BMI and education.
resultsHigh snack cost was significantly associated with a fast increase in the percentage of body fat over time (p trend = 0.04). Adjusted difference in annual increase rate in percentage of body fat between the high and low snack cost group was 0.31% [95% confident interval (CI) 0.04%, 0.58%], after adjusting for potential confounders. The impacts of snack cost on change in the percentage of body fat were more pronounced in boys, younger participants and those with higher BMI z-score at the baseline, relative to their counterparts (p interaction < 0.001 for all).
conclusionsHigh snack cost was associated with more gain of body fat in Chinese school-aged children.
