Effects of a7nAChR agonist on the tissue estrogen receptor expression of castrated rats.
Article in International journal of clinical and experimental pathology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Osteoporosis is one common disease in postmenopausal women due to depressed estrogen level. It has been known that inflammatory factors are involved in osteoporosis pathogenesis. One regulator of inflammatory cascade reaction, a7-nicotinic acetylcholine receptor (a7nAChR), therefore, may exert certain role in osteoporosis. This study thus investigated this question on an osteoporosis rat model after castration. Rats were firstly castrated to induce osteoporosis, and then received a7nAChR agonist (PNU-282987), diethylstilbestrol or saline via intraperitoneal injection. After 6 or 12 weeks, bone samples were collected for counting osteoblast number, bone density and estrogen receptor (ERα and ERβ) expression, in addition to the serum laboratory of inflammatory factors. Bone density, osteoclast number, ERα and ERβ expression level were significantly depressed in model group, and were remarkable potentiated in the drug treatment group (P<0.05). The levels of BGP and PTH in drug treatment group were decreased compared to diethylstilbestrol group, while E2 and IGF-1 showed up-regulation. Agonist of a7nAChR can up-regulate estrogen receptor expression and may prevent the occurrence and development of osteoporosis.
