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

Transfection with a plasmid encoding the 3' untranslated region (3' UTR) of skeletal muscle tropomyosin induces chicken embryonic fibroblasts to express skeletal tropomyosin. Such cells become spindle shaped, fuse, and express titin, a marker of striated muscle differentiation. Skeletal muscle tropomyosin and titin organize in sarcomeric arrays. When the tropomyosin 3' UTR is expressed in osteoblasts, less skeletal muscle tropomyosin is expressed, and titin expression is delayed. Some transfected osteoblasts become spindle shaped but do not fuse nor organize these proteins into sarcomeres. Transfected cells expressing muscle tropomyosin organize muscle and nonmuscle isoforms into the same structures. Thus, the skeletal muscle tropomyosin 3' UTR induces transdifferentiation into a striated muscle phenotype in a cell-type-specific context.
