Pilot Study of Growth Factors in Colostrum: How Delivery Mode and Maternal Health Impact IGF-1, EGF, NGF, and TGF-β Levels in Polish Women.
Article in Nutrients, 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
backgroundBreast milk is the most important nutrition for newborns. Growth factors such as insulin-like growth factor 1 (IGF-1), epidermal growth factor (EGF), transforming growth factor-β (TGF-β), and nerve growth factor (NGF) are among its components that play pivotal roles in neonatal development, immune system priming, and gastrointestinal maturation. This study examined the effects of gestational diabetes mellitus (GDM), maternal hypothyroidism, and method of delivery on the concentrations of these factors in colostrum collected at three distinct postpartum time points.
methodsA group of 39 women was included, 20 of whom gave birth vaginally, whereas caesarean section was performed in 19 patients. A total of 18 volunteers were diagnosed with GDM, and 17 suffered from hypothyroidism. Colostrum samples were collected from the volunteers in the first 3 days after birth under hospital conditions. Growth factors like IGF-1, EGF, NGF, and TGF-β were measured in the samples using commercial immunoenzymatic assays.
resultsNo significant differences were observed in the values of these parameters between the groups of women (with GDM or hypothyroidism and healthy, as well as giving birth naturally and by caesarean section). In addition, the growth factors exhibited good stability within the first few postpartum days (CVs for all studied parameters: in the range of 0.7-5.0%).
conclusionsThe pregnancy disorders that were properly controlled and treated by specialists appeared not to affect the levels of the analyzed growth factors-just like the type of delivery and the day of colostrum collection.
