Leukocyte telomere length and birth characteristics associated with obesity in infancy in a predominantly Latinx cohort.
Article in Pediatric obesity, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundPrevious studies suggest that in utero exposures may impact future weight gain trajectories in infancy. Leukocyte telomere length (LTL) collected at birth may be an additional variable to test in models for childhood obesity as adult studies suggest that LTL may be predictive of metabolic disease.
methodsUsing a primarily Latinx mother-child longitudinal cohort design, we assessed the relationship between newborn LTL measured via quantitative PCR and obesity at 12 months (WFA ≥ 95th percentile). Secondary outcomes included weight-for-age (WFA) Z scores at 12 months and covariates included birth anthropometrics and maternal prenatal health. Logistic and linear regression models were used to assess independent predictors for infant obesity and WFA Z scores.
resultsWe followed 302 children until 12 months including 65.89% with Latinx ethnicity and 4.97% had obesity at 12 months. Independent predictors of obesity at 12 months included higher birthweight Z scores (OR 2.24, 1.16, 5.05) and WFA Z scores at 6 months (OR 1.56, 1.19, 2.05). Longer LTL at birth and higher Apgar scores at 5 min were protective (OR 0.04, 95%CI 0.002, 0.79 and OR 0.30, 95%CI 0.13-0.72, respectively). LTL at birth was negatively associated with WFA Z scores at 12 months of age in multivariable models (Coeff = -0.58, 95%CI -1.05, -0.12).
conclusionsLTL at birth may be a marker, in addition to birthweight, that can be used to assess an infant's risk for subsequent obesity. Future studies are needed to better assess and determine possible maternal exposures associated with shorter newborn LTL.
