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

Previous work has indicated that signals from the floor plate and notochord promote chondrogenesis of the somitic mesoderm. These tissues, acting through the secreted signaling molecule Sonic hedgehog (Shh), appear to be critical for the formation of the sclerotome. Later steps in the differentiation of sclerotome into cartilage may be independent of the influence of these axial tissues. Although the signals involved in these later steps have not yet been pinpointed, there is substantial evidence that the analogous stages of limb bud chondrogenesis require bone morphogenetic protein (BMP) signaling. We show here that presomitic mesoderm (psm) cultured in the presence of Shh will differentiate into cartilage, and that the later stages of this differentiation process specifically depend on BMP signaling. We find that Shh not only acts in collaboration with BMPs to induce cartilage, but that it changes the competence of target cells to respond to BMPs. In the absence of Shh, BMP administration induces lateral plate gene expression in cultured psm. After exposure to Shh, BMP signaling no longer induces expression of lateral plate markers but now induces robust chondrogenesis in cultured psm. Shh signals are required only transiently for somitic chondrogenesis in vitro, and act to provide a window of competence during which time BMP signals can induce chondrogenic differentiation. Our findings suggest that chondrogenesis of somitic tissues can be divided into two separate phases: Shh-mediated generation of precursor cells, which are competent to initiate chondrogenesis in response to BMP signaling, and later exposure to BMPs, which act to trigger chondrogenic differentiation.
