Effect of Obesity on Cognitive Function among School Adolescents: A Cross-Sectional Study.
Article in Obesity facts, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 35 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
objectivesChildhood obesity contributes to the risk of numerous health problems and has become a major global health concern. This study aimed to establish the association between obesity and cognitive function among healthy school adolescents.
methodsThis study was carried out by taking school adolescents (n = 400) from June 2016 to December 2017. The mean age of the participants was 13.93 ± 0.81 years. The students were divided into group A (obese, n = 223) and B (non-obese, n = 177). Cognitive functions were recorded as per study tool of the Cambridge Neuropsychological Test Automated Battery (CANTAB).
resultsSeverely obese students showed a significant delay in cognitive functions as compared to students with normal BMI. Attention Switching Task (AST)-Latency among students with normal BMI was 647.88 ± 137.59 compared to the students with high BMI (685.08 ± 115.92, p = 0.05), AST-Incongruent was 680.78 ± 142.07 versus 726.76 ± 122.31 (p = 0.02), AST-Percent correct trials was 84.31 ± 10.45 versus 78.09 ± 14.87 (p = 0.001), and Intra-Extra Dimensional Set Shift (IED) Total errors among students with normal BMI was 33.93 ± 21.53 compared to the students with high BMI (42.86 ± 37.27, p = 0.03).
conclusionCognitive functions including AST-Latency, AST-Incongruent, AST-Percent correct trials, and IED Total errors were significantly weakened in markedly obese students. Significant impairments in their cognitive functions, especially attention, retention, intelligence, and cognitive flexibility, were observed. The findings of this study emphasize the need to involve school adolescents in physical activities to reduce body weight in order to have cognitive functions within normal range and also to minimize obesity-associated complications.
