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

Alternative splicing is a major mechanism for increasing the range of products encoded by the genome. We recently reported positive identification of the first alternative transcripts (AT) of fatty acid desaturase 3 (FADS3) and FADS2 in fetal and neonatal baboons. FADS3, a putative polyunsaturated fatty acid (PUFA) desaturase gene with no known function, has 7 AT that are expressed in at least twelve organs in an apparently constitutive manner. At least five of seven AT are expressed in several mammals and the chicken. FADS2, catalyzing 6 and 8 desaturation and having multiple PUFA substrates, has one AT that is missing two exons and portions of two others. Semi-quantitative expression estimates reveal at least 20-fold differential expression of FADS2 AT1 among neonatal baboon organs compared to 2-fold in the same organs for the classically spliced (CS) FADS2 transcript. Expression of four of the FADS3 AT, those with missing putatively active domains, is highly correlated among organs, suggesting coordinated coexpression. AT may serve as templates to generate protein isoforms or as signaling molecules, and their widespread detection and expression patterns suggest that they play an important role in PUFA biosynthesis.
