The Effect of Parental Weight and Genetics on the Body Mass Index of Very Low Birth Weight Infants as They Reach School Age.
Observational study in Deutsches Arzteblatt international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPrematurely born individuals are usually of low or normal weight in childhood; in adulthood, however, their probability of being overweight is twice that of persons born at full term. There is not yet any way to predict the weight development of premature babies.
methodsA polygenic BMI score (BMI = body-mass index), calculated from the often very small individual effects of more than 2 million genetic variants, was recently described for adults. We studied the possible association of this score with the course of BMI in premature babies over time, from infancy up to the age of 10-14 years.
results508 individuals were included in the study. At the age of 5-7 years, their mean body weight was 18.8 ± 3.3 kg. The difference between the highest and lowest deciles of the polygenic score was 3.3 kg. At age 10-14, the average body weight was 41.3 ± 11.3 kg, and the difference between the highest and lowest deciles had increased to 9.2 kg. In persons with birth weight under the 10th percentile (n = 68), the difference was 19.2 kg (30.9 kg vs. 50.1 kg). The polygenic BMI score was significantly associated with the BMI z-scores of the overall group and the subgroup of growth-retarded children.
conclusionExtreme values of a polygenic BMI score are strongly associated with the weight development of preterm infants as they develop into children aged 10-14. The large effect size implies that this score may aid in the counseling of prematurely born children and their parents.
