Overcoming resistance to bisphosphonates through the administration of alfacalcidol: results of a 1-year, open follow-up study.
Article in Rheumatology international, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 intended to determine whether the replacement of vitamin D3 with alfacalcidol results in any bone mineral density (BMD) increase in 76 patients unresponsive to the combination of alendronate and conventional vitamin D3 treatment. In these patients the conventional vitamin D3 had been replaced with alfacalcidol (0.5 μg/day), and then the patients were followed up for a year. After treatment for 1 year, Wilcoxon test revealed a small but statistically significant (P < 0.001) increase in the BMD values of the forearm and lumbar vertebrae, in the serum calcium and urinary calcium/creatinine ratio in first-voided morning urine. However, the serum alkaline phosphatase activity, phosphorus, parathormone, osteocalcin levels and the urinary d-pyr/creatinine ratio decreased significantly (P < 0.001). As suggested by our results, combination therapy with alendronate and alfacalcidol increases bone density and improves the biochemical markers of bone turnover, without any substantial increase in the incidence of adverse effects.
