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 orphan nuclear receptor DAX-1 (dosage-sensitive sex reversal-AHC critical region on the X chromosome gene 1; NR0B1) is known for its role in human development, specifically sex determination and steroidogenesis. Several recent publications have described an alternatively spliced form of DAX-1 called DAX-1A ( NR0B1A). DAX-1A is encoded by exons 1 and 2A of DAX-1, with exon 2A located within the DAX-1 intron 1. DAX-1A expression has been observed in several tissues, including adrenal gland, ovary, and testis. Transfection studies have further shown that DAX-1A has an inhibitory effect on DAX-1, suggesting a role for DAX-1A in the regulation of adrenal and gonadal differentiation/function. However, the relative level of DAX-1 versus DAX-1A transcripts still remains unclear. Herein, we developed and performed quantitative real-time RT-PCR to measure DAX-1 and DAX-1A mRNA expression levels in H295R human adrenal carcinoma cell lines, human adult and fetal adrenal glands, corpus luteum, testis, whole pre- and postmenopausal ovaries, ovarian follicles, placenta, liver, and kidney. These mRNA expression levels were quantified using DAX-1 and DAX-1A standard curves. In addition, Western blotting analysis was performed to examine both DAX-1 and DAX-1A protein levels in H295R cells, adrenal glands, corpus luteum, and liver. Both DAX-1 and DAX-1A mRNA were detected in all samples of H295R cells, human fetal and adult adrenals, testis, ovary, ovarian follicles, and corpus luteum. However, DAX-1 mRNA levels were significantly higher (> 37-fold) than that seen for DAX-1A (p<0.01). DAX-1A mRNA expression levels were undetectable in human liver, placenta, and kidney. Western blotting analysis results demonstrated that DAX-1 protein was predominantly expressed in H295R cells, human adult adrenal, and corpus luteum. These results suggest that in comparison to DAX-1A, DAX-1 is, by far, the predominant mRNA isoform found in human adrenal glands and gonads.
