[Impact of body composition and psychological state on executive functions in individuals with obesity].

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
backgroundThis study aimed to examine the relationship between anthropometric and psychological variables and executive functions in individuals with obesity.
methodAdults with obesity were recruited in Alicante (Spain). Participants underwent interviews to collect sociodemographic data (sex, age, educational level, marital status, and employment status) and anthropometric assessments measuring weight, body mass index, visceral fat, fat mass, and muscle mass. Psychological evaluations were carried out using the DASS-21. Executive functions were assessed through the M-WCST (cognitive flexibility), WAIS-IV (working memory), TMTA (processing speed), and TMTB (inhibitory control).
resultsThe sample comprised 48 participants (52% female) with a mean age of 47.58 years. Most participants had secondary education, were married, and employed. Women exhibited higher values in weight, body mass index, and fat mass (% and kg). Multiple linear regression analyses revealed that anthropometric variables -weight, body mass index, visceral fat, fat mass, and muscle mass- significantly influenced performance on working memory, processing speed, and inhibitory control performance. Additionally, anxiety levels were associated with cognitive flexibility and working memory, while depression levels were linked to inhibitory control.
conclusionsAnthropometric variables -weight, body mass index, visceral fat, fat mass, and muscle mass- are associated with variations in executive function performance, particularly in working memory, processing speed, and inhibitory control. Psychological states -anxiety and depression- are related to specific aspects of executive functioning.
