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

The vitamin D receptor (VDR) is crucial for virtually all of vitamin D's actions and is thought to be ubiquitously expressed. We hypothesized that disruption of one allele of the VDR gene would impact bone development and would have metabolic consequences. Body composition and bone mass (BMD) in VDR heterozygous (VDR HET) mice were compared to those obtained in male and female VDR KO and WT mice at 8 weeks of age. Male mice were also evaluated at 16 weeks, and bone marrow mesenchymal stem cell (MSC) differentiation was evaluated in VDR female mice. Additionally, female VDR HET and WT mice received intermittent PTH treatment or vehicle (VH) for 4 weeks. BMD was determined at baseline and after treatment. MRI was done in vivo at the end of treatment; μCT and bone histomorphometry were performed after killing the animals. VDR HET male mice had normal skeletal development until 16 weeks of age but showed significantly less gain in fat mass than WT mice. In contrast, female VDR HET mice showed decreased total-body BMD at age 8 weeks but had a normal skeletal response to PTH. MSC differentiation was also impaired in VDR HET female mice. Thus, female VDR HET mice show early impairment in bone acquisition, while male VDR HET mice exhibit a lean phenotype. Our results indicate that the VDR HET mouse is a useful model for studying the metabolic and skeletal impact of decreased vitamin D sensitivity.
