Belgian primary school children's hydration status at school and its personal determinants.
Observational study in European journal of nutrition, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers, 1 of them a synthesis that pooled 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeDehydration has been related to several health aspects, and children are especially vulnerable. Since children spend a large time at school, we aim to examine children's hydration status at school-start and its change during the school-day by objective measures. To identify subpopulations at risk, determinants of hydration were tested.
methodsIn 371 Belgian 7-13-year-old children, hydration was measured by (1) urinary osmolality at school-start and by a pooled school-day sample; (2) body water% by impedance; (3) parental reported beverage consumption; (4) urination frequency. Linear regression analyses were used to test putative predictors of hydration status: age, sex, parental education, region (Dutch-speaking versus French-speaking part of Belgium), diet quality and adiposity.
resultsA mean osmolality of 888 mosmol/kg was found in the school-start sample and 767 mosmol/kg in the school-day sample. This resulted in, respectively, 76 and 54 % of the children being dehydrated (>800 mosmol/kg). In 45 % of the children, the hydration level decreased over the school-day. Also the body water% as derived from bio-impedance (57 % ±4), the reported average daily beverage intake (911 ml) and the lower urination frequency during weekdays versus weekend days confirmed the low hydration status in our school population. Boys, Walloon children and those with higher adiposity were at increased risk of low hydration level. Diet quality was not the predictor of hydration status.
conclusionsHydration status at school appeared problematic in this population. This emphasizes the need for more resources and attention by school management and governmental organizations. Herein, especially Walloon schools and boys should be reached.
