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

The splicing variant, 5T allele, in intron 8 of the cystic fibrosis transmembrane conductance regulator (CFTR) gene was shown to be associated with partial penetrance of the clinical expression. This splicing variant leads to two possible transcripts: one normal and the other aberrantly spliced that lacks exon 9. The aim of this study was to analyze the molecular basis of the partial penetrance in individuals carrying the 5T allele. We analyzed the level of the correctly spliced RNA transcribed from the 5T allele in nasal and epididymal epithelium and correlated it with disease expression. Semiquantitative nondifferential reverse-transcriptase-PCR showed a considerable variability (6%-37%) in the total level of correctly spliced RNA transcribed from the 5T allele in nasal epithelium from 11 patients. A significant nonlinear correlation (r = .82, P = .002) between the level of the normal CFTR transcripts and the severity of lung disease was shown. No individuals with normal lung function and minimal or no lung disease (FEV1 >80% predicted) had <25% of normal transcripts, and individuals with <15% of normal transcripts did not have FEV1 >80%. The level of normal transcripts in epididymal epithelial cells from four infertile males with congenital bilateral absence of the vas deferens was low (6%-24%). In infertile males with normal lung function the level of correctly spliced transcripts in the nasal epithelium was higher than the level in the epididymal epithelium. These results indicate that there is variability in the efficiency of the splicing mechanism, among different individuals and between different organs of the same individual. This variability provides the molecular basis of the partial penetrance of cystic fibrosis disease in patients carrying the 5T allele.
