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
Luciferase reporter plasmids (pGL3 backbone, Promega) have been utilized to characterize the transcriptional effects of the environmental contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and other aryl hydrocarbon receptor (AhR) ligands. Following ligand activation, the AhR and its dimerization partner AhR nuclear translocator (ARNT) regulate transcription by binding dioxin response elements (DREs) in regulatory regions of dioxin-sensitive genes. Upon sequencing of our luciferase reporters, we unexpectedly identified a DRE core motif within the multiple cloning site (mcsDRE) of the pGL3 luciferase plasmid backbone in a subset of our reporters. Therefore, the objective of this study was to determine if the mcsDRE inadvertently influences reporter activity. Utilizing deletional analysis we determined that the mcsDRE did significantly alter the transcriptional effect induced by TCDD. Since many chemicals have been shown to interact with the AhR and influence transcription through the DRE, the presence of the mcsDRE in the pGL3 luciferase plasmid may inappropriately influence promoter and enhancer analysis. As such, insertion of regulatory elements into pGL3 reporters should be designed to avoid retaining the mcsDRE core motif (GCGTG) and currently utilized pGL3 reporters should be evaluated for the presence of the mcsDRE.
