Transient modulation of calcium and parathyroid hormone stimulates bone formation.
Article in Endocrine, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Intermittent administration of parathyroid hormone can stimulate bone formation. Parathyroid hormone is a natural hormone that responds to serum calcium levels. In this study, we examined whether a transient increase and/or decrease in the serum calcium can stimulate bone formation. Using a mathematical model previously developed, we first predicted the effects of administration of parathyroid hormone, neutralizing parathyroid hormone antibody, calcium, and EGTA (calcium chelator) on the serum concentration of parathyroid hormone and calcium. The model predicted that intermittent injection of parathyroid hormone and ethylene glycol tetraacetic acid transiently elevated the serum parathyroid hormone, while that of parathyroid hormone antibody and calcium transiently reduced parathyroid hormone in the serum. In vitro analysis revealed that parathyroid hormone's transient changes (both up and down) elevated activating transcription factor 4-mediated osteocalcin expression. In the mouse model of osteoporosis, both intermittent administration of calcium and ethylene glycol tetraacetic acid showed tendency to increase bone mineral density of the upper limb (ulna and humerus) and spine, but the effects varied in a region-specific manner. Collectively, the study herein supports a common bone response to administration of calcium and its chelator through their effects on parathyroid hormone.
