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
The purpose of this study was to evaluate salmon calcitonin (sCT) microspheres in vitro for their antiresorptive activity using cultured osteoclastic cells. The antiresorptive activity of sCT-loaded microspheres, prepared from a low molecular weight hydrophilic poly (lactide-co-glycolide) polymer (PLGA), was studied using bone marrow culture cells harvested from juvenile rats and cultured on slices of devitalized bone for up to 4 weeks. The resorptive activity of osteoclastic cells was quantified in terms of number and type of resorption pits and total area of resorption. Microspheres containing 5.1% sCT released 70% peptide in 2 weeks and 88% in 4 weeks. All sCT treatments inhibited total resorptive activity. A dose-dependent decrease in resorption was observed with sCT microspheres at 2 weeks. The high dose (10 mg of microspheres) produced a 99.5% decrease in resorption at 3 weeks, while the low dose (1 mg) produced an 80% reduction. Exposure of cultures to soluble sCT and sCT-loaded microspheres caused a decrease in the number of large pits, which were the predominant type formed in control cultures. Thus, this system could serve as an in vitro method to evaluate the antiresorptive effect of PLGA-sCT microspheres.
