An In Vitro and In Vivo Study of Thyroid Disruption of 1,2-Bis(2,4,6-tribromophenoxy)ethane (BTBPE)-A Novel Brominated Flame Retardant.
Article in Environment & health (Washington, D.C.), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The novel brominated flame retardant, 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), is an emerging environmental pollutant with undetermined toxicity. We investigated how BTBPE causes thyroid endocrine disruption with integrated in silico, in vitro, and in vivo assays. In yeast two-hybrid and T-Screen assays, BTBPE interacted with zebrafish thyroid hormone receptors with binding energies weaker than the TR agonist-3,3',5-Triiodo-l-thyronine (T3), and disrupted thyroid function as a thyroid receptor (TR) agonist. We examined the bioconcentration, developmental toxicity, and thyroid endocrine disruption in zebrafish after a 14-day exposure to BTBPE (1, 3, 10 μg/L). Thyroxine (T4) was lower in BTBPE-treated larvae, whereas corticotropin-releasing hormone (CRH) and thyroid-stimulating hormone (TSH) were higher. The gene transcription alterations along the hypothalamic-pituitary-thyroid (HPT) axis were observed. Furthermore, reduced locomotion suggested that BTBPE imparts developmental neurotoxicity at zebrafish early developmental stage. Establishing that BTBPE has thyroid endocrine-disrupting effects is an important step for understanding and managing BTBPE toxicity.
