Transcription termination sequences support the expression of transgene product secreted with milk.
Article in Transgenic research, 2019. 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
Expression of the reporter gene in transgenic animals depends on the surrounding chromatin environment. Recent genome-wide studies have shown that, in mammals, the entire genome is transcribed. Transcription through a transgene often has a negative effect on the expression of a reporter gene. Here, we compared the ability of well-studied chicken chromatin insulator HS4 and bidirectional transcription terminators from the human genome to support high-level expression of the firefly luciferase gene (Fluc) under control of the previously characterized goat β-casein gene promoter. The insertion of HS4 or either of the two transcription terminators upstream of the promoter resulted in tenfold enhancement of Fluc expression in the mammary glands of transgenic mice. These results suggest that transcriptional terminators, similar to the HS4 insulator, can be used to improve the reporter gene expression in transgenic animals.
