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

unlabelledThe purpose of this study is to investigate the anti-osteoporotic effects of Radix Dipsaci total saponins (RTS). We showed that RTS was able to improve bone properties by either an increase of osteoblastic activity or a decrease in osteoclastic activity.

introductionRadix Dipsaci has long been used as an anti-osteoporotic drug. The present study investigates the anti-osteoporotic effects of RTS.

methodsThree-month-old female rats were randomly assigned into a sham-operated group (sham) and five ovariectomy (OVX) subgroups, namely, OVX with vehicle (OVX), OVX with 17β-ethinylestradiol (E(2)), and OVX with graded doses of RTS (50, 100, or 200 mg/kg/d). RTS and E(2) were administered orally, daily from 1 week after OVX treatment for 4 months. Bone mass, turnover, and strength were evaluated by dual-energy X-ray absorptiometry, biochemical markers, and the three-point bending test. The trabecular bone microarchitecture was assessed by microCT. In vitro experiments were performed to determine the potential molecular mechanisms of the anti-osteoporotic effect of RTS.

resultsRTS prevented the loss of bone mass induced by OVX. The preventive effect on bone loss was primarily indicated by decreasing levels of bone turnover markers and confirmed by the changes in urinary calcium and phosphorus excretion. The treatment also enhanced the biomechanical strength of bone and prevented the deterioration of trabecular bone microarchitecture. RTS induced MC3T3-E1 and primary osteoblastic cell maturation and differentiation and increased bone formation by increasing BMP-2 synthesis. In addition, RTS inhibited osteoclastogenesis through an increase in osteoprotegrin and a decrease in NF-kB ligand expression in vitro.

conclusionsRTS treatment can effectively suppress the loss of bone mass induced by OVX and in vitro evidence suggests this could be through actions on both osteoblasts and osteoclasts.
