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

Osteoporosis (OP) behaves in different manners in different parts of the skeleton. This study aims to investigate the effects of curcumin on bone mass of the mandibular and femur from ovariectomized OP rats and to validate whether enhancer of zeste homolog 2 (EZH2)/Wnt/β-Catenin pathway is involved in this process. Curcumin was administered intragastrically into ovariectomized rats for 12 weeks. The bone parameters and the morphology of the trabecular bone of the left mandible and left femur were assessed by micro-computed tomography assay. Morphological changes of the left mandible and left femur were evaluated by hematoxylin and eosin staining. The mRNA levels of EZH2, β-Catenin, and Runx2 in the right mandible and right femur were examined by quantitative real-time polymerase chain reaction. Immunohistochemistry was performed to assess EZH2 expression. Both the mandible and femur exhibited OP-like changes in ovariectomized rats, while the mandible bone resorption was less than the femur bone resorption. Curcumin intragastric administration improved bone microstructure and promoted bone formation in the mandible and femur. Curcumin inhibited EZH2 mRNA level and induced that of β-Catenin and Runx2 in the mandible and femur. Collectively, curcumin exerts protective effects against OP, possibly by regulating the EZH2/Wnt/β-Catenin pathway.
