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

Retinoic acid is a signaling molecule involved in the regulation of growth and morphogenesis during development. There are three types of nuclear receptors for all-trans retinoic acid in mammals, RAR alpha, RAR beta, and RAR gamma, which transduce the retinoic acid signal by inducing or repressing the transcription of target genes (Leid, M., P. Kastner, and P. Chambon. 1992. Trends Biochem. Sci. 17:427-433). While RAR alpha, RAR beta, and RAR gamma are expressed in distinct but overlapping patterns in the developing mouse limb, their exact role in limb development remains unclear. To better understand the role of retinoic acid receptors in mammalian limb development, we have ectopically expressed a modified RAR alpha with constitutive activity (Balkan, W., G.K. Klintworth, C.B. Bock, and E. Linney. 1992. Dev. Biol. 151:622-625) in the limbs of transgenic mice. Overexpression of the transgene was associated with marked pre- and postaxial limb defects, particularly in the hind limb, where expression of the transgene was consistently seen across the whole anteroposterior axis. The defects displayed in these mice recapitulate, to a large degree, many of the congenital limb malformations observed in the fetuses of dams administered high doses of retinoic acid (Kochhar, D.M. 1973. Teratology. 7:289-295). Further analysis of these transgenic animals showed that the defect in skeletogenesis resided at the level of chondrogenesis. Comparison of the expression of the transgene relative to that of endogenous RAR alpha revealed that downregulation of RAR alpha is important in allowing the chondrogenic phenotype to be expressed. These results demonstrate a specific function for RARalpha in limb development and the regulation of chondroblast differentiation.
