OPG inhibits gene expression of RANK and CAII in mouse osteoclast-like cell.
Article in Rheumatology international, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
This study was designed to determine the effects of the osteoprotegerin (OPG) on the mRNA expression of carbonic anhydrase II (CAII) and the receptor activator of NF-κB (RANK) in mouse osteoclast-like cells. Marrow cells were harvested from femora and tibiae of mouse and cultured in 6-well chamber slides. After 1 day of incubation, the marrow cells were exposed to M-CSF (25 ng/ml), RANKL (50 ng/ml), and different concentrations of OPG (50, 75, and 100 ng/ml, respectively) for 3 days. Osteoclast-like cells were confirmed by both tartrate-resistant acid phosphatase (TRAP) stain and bone resorption assay. The expression of RANK and CAIImRNA was determined with real-time fluorescent quantitative polymerase chain reaction. The numbers of multinucleated, TRAP-positive osteoclast-like cells, and resorption pits formed were observed. Compared with the M-CSF + RANKL group, RANKmRNA expression was statistically decreased in the M-CSF and M-CSF + RANKL + OPG (100 ng/ml) groups (P = 0.004, P = 0.024, respectively); Compared with the M-CSF, M-CSF + RANKL, and M-CSF + RANKL + OPG (100 ng/ml) group, CAIImRNA expression in the M-CSF + RANKL + OPG (75 ng/ml) groups was statistically decreased (P = 0.001, P = 0.008, and P = 0.036, respectively). These data suggest that OPG could regulate the expression of RANK and CA II mRNA in the marrow culture system.
