Paternal contributions to telomere reprogramming in fetal development.
Article in International journal of biochemistry and molecular biology, 2025. 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
objectivesTelomere length, the markers of biological aging, can be influenced by risk factors that may lead to health issues like chronic non-communicable diseases. This study explored the paternal telomere length influenced by diseases like diabetes and hypertension with age and its association with newborn telomere length (TL) and the telomerase gene.
methodsIn this cross-sectional study, 204 father-newborn dyads were recruited. The qPCR was used for the quantification of TL (T/S ratio), and Sanger sequencing was done for telomerase (TERT) genotype identification. Statistical Package for Social Sciences (SPSS) and GraphPad Prism Software were used for data analysis. The Spearman correlation was used to find an association between father and newborn TL. The Kruskal-Wallis and Mann-Whitney test was used to find differences among disease groups and TL. The P<0.05 was considered statistically significant.
resultsA positive correlation (r=0.39) (P<0.0001) was seen among fathers and newborn TL. The mean TL (T/S ratio) was found to be longer in healthy fathers and their newborns (1.67±1.18, 2.36±1.39), whereas significantly shorter TL (1.41±0.98, 2.02±1.58) (P=0.000) was seen in fathers suffering from diseases. The healthy fathers and their newborns TL (2.94±0.72, 3.10±0.61) were seen longer in the 15-20 (yrs) age category. Moreover, newborns of fathers (41-45 yrs) with both diabetes and hypertension had significantly longer telomere length (3.20±2.92) compared to their fathers (1.15±1.65) (P=0.006). The TERT risk genotype AC (rs2736100) was the most prevalent among the newborn girls.
conclusionA positive association with shorter TL in newborns was found in fathers having chronic diseases such as diabetes and hypertension, highlighting the contribution of fathers in reprogramming newborns' telomere biology.
