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

Cystic fibrosis (CF) is a lethal genetic disorder that is due to mutations in the gene encoding the cAMP-activated anion CF transmembrane conductance regulator (CFTR) channel. A three-nucleotide base deletion (TTT), encoding phenylalanine in position 508 of the translatable CFTR sequence (accompanied by a C to T replacement immediately 5' to the deletion), accounts for approximately 75% of cases of the disease. In the present study, an oligonucleotide complex (CF4-CF6, 2'-0-methyl RNA-unmodified RNA oligonucleotide duplex, respectively) was used to restore CFTR function by insertion of missing bases in Delta508 CFTR mRNA from a cultured (Delta508) cell line. cAMP-activated whole-cell currents and Cl- transport were detected in CF4-CF6-treated, but not control Delta508, cells by patch-clamp and 6-methoxy-N-(3-sulfopropyl)quinolinium fluorescence (SPQ) quenching analyses, respectively. Further, the nucleotide addition in the deleted region of Delta508 CFTR was determined after amplification by RT-PCR. Insertion of UGU and replacement of U by C immediately 5' to the deletion site in Delta508 mRNA appear to have taken place, with phenotypic but not genotypic reversion in tissue culture of treated cells. The mechanism of insertion of nucleotides has yet to be determined.
