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

Bone metabolism disorder has been identified to play a vital role in the pathogenesis of glucocorticoid-induced osteoporosis (GIOP). The local renin-angiotensin system (RAS) in bone is newly defined to be closely related to the bone metabolism. However, it is unknown whether the local RAS is involved in GIOP. Adult male New Zealand white rabbits were treated with saline, dexamethasone (DXM) alone, or DXM combined with perindopril. The expression of main RAS components in trabecular bone was examined at mRNA and/or protein levels. Bone metabolism was analyzed using dual-energy X-ray absorptiometry, histomorphometry, biomechanics, biochemical techniques, and quantitative RT-PCR. The expressions of local bone angiotensin II, angiotensin types 1 and 2 receptors, and angiotensin-converting enzyme at mRNA and/or protein levels increased when DXM-induced osteoporosis was present. Whereas, perindopril significantly blocked the activation of the local RAS and partially reversed GIOP. Mineralizing surface, mineral apposition rate, and bone formation rate were decreased by DXM, along with serum osteocalcin being downregulated. These changes were then reversed by the use of perindopril. Osteoclast number, osteoclast surface, and eroded surface increased after the administration of DXM, and urinary deoxypyridinoline was upregulated. These were also inhibited when perindopril was given. Quantitative RT-PCR using RNA isolated from the lumbar vertebrae revealed an increase in the SOST expression and a decrease in the Runx2 expression, whereas the receptor activator of nuclear factor-κB ligand/osteoprotegerin ratio and the expression of tartrate resistant acid phosphatase were increased, which were all inhibited by perindopril. The results of this study provide evidence for the role of local RAS is involved in GIOP, and GIOP may be ameliorated by blocking the activation of local RAS in the bone.
