Article in Journal of orthopaedic translation, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
ethnopharmacological relevanceOestrogen deficiency, high incidences of hyperlipidaemia (HLP) and accelerated bone loss frequently occur in postmenopausal women. There is an urgent need to develop functional foods or specific drugs to protect against bone loss induced by oestrogen deficiency with HLP. AIM OF THE STUDY: In this study, we investigated the potential inhibitory effects of MATERIALS AND
methodsThe rats were treated for 12 weeks, and then, bone mineral density, bone biomechanical, bone microstructure, bone morphology, biomarkers of HLP oxidative stress and side effects were determined. Immunohistochemical staining and Western blot were performed to evaluate related protein expression.
resultsThe femur bone mineral density increased (P < 0.05), and the microscopic structures (ratio of bone volume to total volume [BV/TV], connectivity density [Conn.D], trabecular number [Tb.N] and trabecular thickness [Tb.Th]) of the bone trabecula and mechanical properties (maximum and breaking load [ML and BL, respectively]) improved after SI treatment (P < 0.05). Furthermore, the levels of HLP biomarkers (total cholesterol, triglyceride and low-density lipoprotein) were significantly decreased (P < 0.05), whereas the levels of antioxidant markers (superoxide dismutase and total antioxidant capacity) were increased (P < 0.05). Similar results were obtained with immunohistochemical staining, whereas the Western blot assay showed that SI stimulated the expression of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) in bone.
conclusionOur data indicate that rats exposed to SI treatment for 12 weeks did not exhibit noticeable side effects. In conclusion, SI suppressed bone loss induced by ovariectomized and the associated HLP in rats by activating Nrf2, which could be a promising treatment option for osteoporosis induced by oestrogen deficiency and HLP in postmenopausal women. TRANSLATIONAL SCOPE STATEMENT: Our study verified that SI prevented bone loss in rats with oestrogen deficiency with HLP by upregulating nuclear factor (erythroid-derived 2)-like 2. Furthermore, no side effect was observed after the long-term administration of SI. Those results suggested SI could be developed as a functional food or drug for postmenopausal osteoporosis induced by oestrogen deficiency with HLP.
