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

In hyperlipidemia, oxidized lipids accumulate in vascular tissues and trigger atherosclerosis. Such lipids also deposit in bone tissues, where they may promote osteoporosis. We found previously that oxidized lipids attenuate osteogenesis and that parathyroid hormone (PTH) bone anabolism is blunted in hyperlipidemic mice, suggesting that osteoporotic patients with hyperlipidemia may develop resistance to PTH therapy. To determine if oxidized lipids account for this PTH resistance, we blocked lipid oxidation products in hyperlipidemic mice with an ApoA-I mimetic peptide, D-4F, and the bone anabolic response to PTH treatment was assessed. Skeletally immature Ldlr(-/-) mice were placed on a high-fat diet and treated with D-4F peptide and/or with intermittent PTH(1-34) injections. As expected, D-4F attenuated serum lipid oxidation products and tissue lipid deposition induced by the diet. Importantly, D-4F treatment attenuated the adverse effects of dietary hyperlipidemia on PTH anabolism by restoring micro-computed tomographic parameters of bone quality-cortical mineral content, area, and thickness. D-4F significantly reduced serum markers of bone resorption but not bone formation. PTH and D-4F, together but not separately, also promoted bone anabolism in an alternative model of hyperlipidemia, Apoe(-/-) mice. In normolipemic mice, D-4F cotreatment did not further enhance the anabolic effects of PTH, indicating that the mechanism is through its effects on lipids. These findings suggest that oxidized lipids mediate hyperlipidemia-induced PTH resistance in bone through modulation of bone resorption.
