1 · What the graph read from it

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.

2 · The registry

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

backgroundBisphenol A (BPA) is an endocrine-disrupting chemical that may contribute to development of obesity and metabolic disorders. Humans are constantly exposed to low concentrations of BPA, and studies support that the developmental period is particularly sensitive.

objectivesThe aim was to investigate the effects of low-dose developmental BPA exposure on metabolic parameters in male and female Fischer 344 (F344) rat offspring.

methodsPregnant F344 rats were exposed to BPA via their drinking water, corresponding to 0.5 μg/kg BW/d (BPA0.5; <em>n</em>=21) or 50 μg/kg BW/d (BPA50; <em>n</em>=16), from gestational day (GD) 3.5 until postnatal day (PND) 22, and controls were given vehicle (<em>n</em>=26). Body weight (BW), adipose tissue, liver (weight, histology, and gene expression), heart weight, and lipid profile were investigated in the 5-wk-old offspring.

resultsMales and females exhibited differential susceptibility to the different doses of BPA. Developmental BPA exposure increased plasma triglyceride levels (0.81&plusmn;0.10 mmol/L compared with 0.57&plusmn;0.03 mmol/L, females BPA50 <em>p</em>=0.04; 0.81&plusmn;0.05 mmol/L compared with 0.61&plusmn;0.04 mmol/L, males BPA0.5 <em>p</em>=0.005) in F344 rat offspring compared with controls. BPA exposure also increased adipocyte cell density by 122% in inguinal white adipose tissue (iWAT) of female offspring exposed to BPA0.5 compared with controls (68.2&plusmn;4.4 number of adipocytes/HPF compared with 55.9&plusmn;1.5 number of adipocytes/HPF; <em>p</em>=0.03) and by 123% in BPA0.5 females compared with BPA50 animals (68.2&plusmn;4.4 number of adipocytes/high power field (HPF) compared with 55.3&plusmn;2.9 number of adipocytes/HPF; <em>p</em>=0.04). In iWAT of male offspring, adipocyte cell density was increased by 129% in BPA50-exposed animals compared with BPA0.5-exposed animals (69.9&plusmn;5.1 number of adipocytes/HPF compared with 54.0&plusmn;3.4 number of adipocytes/HPF; <em>p</em>=0.03). Furthermore, the expression of genes involved in lipid and adipocyte homeostasis was significantly different between exposed animals and controls depending on the tissue, dose, and sex.

conclusionsDevelopmental exposure to 0.5 μg/kg BW/d of BPA, which is 8-10 times lower than the current preliminary EFSA (European Food Safety Authority) tolerable daily intake (TDI) of 4 μg/kg BW/d and is within the range of environmentally relevant levels, was associated with sex-specific differences in the expression of genes in adipose tissue plasma triglyceride levels in males and adipocyte cell density in females when F344 rat offspring of dams exposed to BPA at 0.5 μg/kg BW/d were compared with the offspring of unexposed controls. https://doi.org/10.1289/EHP505.
