Nutritional risk factors and eating behaviors in adolescents with pectus excavatum: new approach by using cluster analysis.
Article in Pediatric surgery international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThis study aimed to assess eating behaviors, dietary habits, and nutritional history in adolescents with pectus excavatum, and to examine the relationships between anthropometric, biochemical, and behavioral variables using multivariate cluster analysis.
methodsA total of 25 adolescents (21 males, 4 females) aged 11–18 years with a diagnosis of pectus excavatum participated in this cross-sectional study. Data were collected through sociodemographic surveys, anthropometric measurements, serum ferritin levels, and the Adolescent Eating Behavior Assessment Scale. Cluster analysis was applied to identify patterns between nutritional, anthropometric, biochemical, and behavioral factors.
resultsMalnutrition was observed in 16% of participants, thinness in 20%, and short stature in 16%. Low serum ferritin levels were found in 20% of the cohort. Nutritional problems were reported by 72% of adolescents, mainly appetite loss (55.6%) and food neophobia (44.4%). Only 44% had been breastfed up to two years, and the majority (96%) exhibited moderate eating behaviors. Cluster analysis revealed two main clusters linking nutritional and behavioral variables with biochemical status and lifestyle factors.
conclusionThis study is the first to highlight the relationship between eating behaviors, breastfeeding duration, and daily meal frequency in adolescents with pectus excavatum. The findings emphasize the importance of early nutritional assessment and tailored interventions to support growth and overall health in this population.
