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
Chemerin is a recently identified adipokine implicated in appetite regulation and energy metabolism. This study aimed to investigate the relationship between serum chemerin levels, nutritional status, and appetitive traits in early childhood. This cross-sectional study included 85 children aged 2-9 years. Appetite-related traits were assessed using the Child Eating Behavior Questionnaire (CEBQ). Anthropometric measurements were obtained, and fasting venous blood samples were collected for biochemical analyses, including serum chemerin levels. Based on the CEBQ results, participants with a food approach score below 39.50 and a food avoidant score above 58.50 were classified as having appetite-related undernutrition (n = 44) and the others as normal appetite (n = 41). Biochemical and anthropometric parameters, as well as chemerin levels, were compared between the two groups. In addition, correlation analyses were conducted to examine the relationships between chemerin levels and biochemical parameters, anthropometric measurements, and CEBQ scores. Serum chemerin concentrations were significantly lower in children with appetite-related undernutrition compared with those with normal appetite (median [IQR] 562.4 [12.6-946.6] vs. 1264.9 [976.3-1765.0] ng/L, p < 0.05). Chemerin levels were positively correlated with food approach traits and inversely correlated with food avoidance traits. Moreover, positive associations were observed with LDL cholesterol, total cholesterol, albumin, and calcium levels.
conclusionSerum chemerin levels were significantly lower in children with appetite-related undernutrition and were associated with both anthropometric measures and appetitive traits, suggesting a link between chemerin and nutritional status in early childhood. WHAT IS KNOWN: • Chemerin is an adipokine involved in energy metabolism, adipogenesis, and inflammatory processes. • Elevated chemerin levels have been reported in obesity and metabolic disorders, but data on appetite status in children are limited. WHAT IS NEW: • This is the first study evaluating serum chemerin levels according to appetite status in healthy children. • Children with appetite-related undernutrition had significantly lower chemerin levels, associated with anthropometric and appetite-related traits.
