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

Hyperlipidemia increases the risk for generation of lipid oxidation products, which accumulate in the subendothelial spaces of vasculature and bone. Atherogenic high-fat diets increase serum levels of oxidized lipids, which are known to attenuate osteogenesis in culture and to promote bone loss in mice. In this study, we investigated whether oxidized lipids affect bone regeneration and mechanical strength. Wild-type (WT) and hyperlipidemic (Ldlr(-/-)) mice were placed on a high-fat (HF) diet for 13 weeks. Bilateral cranial defects were introduced on each side of the sagittal suture, and 5 weeks postsurgery on the respective diets, the repair/regeneration of cranial bones and mechanical properties of femoral bones were assessed. MicroCT and histological analyses demonstrated that bone regeneration was significantly impaired by the HF diet in WT and Ldlr(-/-) mice. In femoral bone, cortical bone volume fraction (bone volume [BV]/tissue volume [TV]) was significantly reduced, whereas cortical porosity was increased by the HF diet in Ldlr(-/-) but not in WT mice. Femoral bone strength and stiffness, measured by three-point bending analysis, were significantly reduced by the HF diet in Ldlr(-/-), but not in WT mice. Serum analysis showed that the HF diet significantly increased levels of parathyroid hormone, tumor necrosis factor (TNF)-α, calcium, and phosphorus, whereas it reduced procollagen type I N-terminal propeptide, a serum marker of bone formation, in Ldlr(-/-), but not in WT mice. The serum level of carboxyl-terminal collagen crosslinks, a marker for bone resorption, was also 1.7-fold greater in Ldlr(-/-) mice. These findings suggest that hyperlipidemia induces secondary hyperparathyroidism and impairs bone regeneration and mechanical strength.
