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

Current treatment options for osteoporosis primarily involve pharmacotherapies, but they are often accompanied by undesirable side effects. Utilization of mechanical stress which can noninvasively induce bone formation has been suggested as an alternative to conventional treatments. Here, we examined the efficacy of mechanical stress induced by electrical stimulation, radial extracorporeal shock waves, and ultrasound for estrogen-deficient osteoporosis. Female Wistar rats were divided into following five groups: sham-operated group, untreated after ovariectomy, and treated with electrical stimulation, radial extracorporeal shock wave, or ultrasound starting at 8 weeks after ovariectomy for 4 weeks. Trabecular bone architecture of the femur was assessed by micro-CT and its biomechanical properties were obtained by mechanical testing. The femurs were further evaluated by histochemical, immunohistochemical, and real-time PCR analyses. Radial extracorporeal shock wave and ultrasound treatment improved trabecular bone microarchitecture and bone strength in osteoporotic rats, but not electrical stimulation. The shock wave decreased osteoclast activity and RANKL expression. The exposure of ultrasound increased osteoblast activity and β-catenin-positive cells, and they decreased sclerostin-positive osteocytes. These findings suggest that mechanical stress induced by radial extracorporeal shock wave and ultrasound can improve estrogen-deficient bone loss and bone fragility through promoted bone formation or attenuated bone resorption.
