Vitamin d status and response to initial vitamin d supplementation in korean women with osteoporosis.
Article in Journal of bone metabolism, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThe aim of this study is to evaluate whether the optimal vitamin D level is achieved after taking recommended dose in vitamin D deficient patients.
methodsThis was a retrospective study. Women (n=52) first diagnosed with osteoporosis were recruited in outpatient clinic. They were recommended to be exposed to sun light for more than 30 min a day. Subjects were divided into 3 groups according to serum 25-hydroxy-vitamin D3 (25-[OH]D3) status: deficiency (less than 20 ng/mL), insufficiency (20-30 ng/mL) and sufficiency (30 ng/mL or more). Insufficient and sufficient patients received the recommended dose (1,000 IU/day) but deficient patients received recommended or double dose (1,800-2,000 IU/day). We compared 25-(OH)D levels at baseline and after vitamin D supplementation for 3 months.
resultsMedian (interquartile range) serum 25-(OH)D concentration at baseline was 15.10 (13.30-16.97) ng/mL and the proportion of deficient, insufficient and sufficient groups were 69.2%, 23.1%, and 7.7% respectively. The optimal 25-(OH)D level (30 ng/mL or more) was achieved in 83.3% of insufficient patients with the recommended dose and was did in 55.6% of deficient patients with recommended dose (P=0.117). However, 88.9% of the deficient patient with double dose achieved optimal level (P=0.030).
conclusionsAbout 44% of vitamin D deficient patients did not attain the optimal level of serum 25-(OH)D despite recommended daily intake of vitamin D to 1,000 IU in patients with osteoporosis. Follow-up of serum 25-(OH)D levels may be required for vitamin D supplementation in vitamin D deficient patients with osteoporosis.
