Discrepant association of serum C-3 epimer of 25-hydroxyvitamin D versus non-epimeric 25-hydroxyvitamin D with serum lipid levels.
Article in Lipids in health and disease, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundLow vitamin D status has been associated with a number of chronic diseases. For dyslipidemia, vitamin D deficiency has been associated with higher low density lipoprotein-cholesterol (LDL-C) in a number of studies, but with inconsistent results in clinical trials. The purpose of the present study is to explore the relative importance of 3-epi-25-hydroxyvitamin D (25(OH)D) as compared with the non-epimeric form in relation to serum lipid.
methodThis study used data from 1068 randomly selected volunteers in the Thai 4(th) National Health Examination Survey (NHES IV). Serum 25(OH)D2, 25(OH)D3, 3-epi-25(OH)D2 and 3-epi-25(OH)D3 were analyzed by liquid chromatography-tandem mass spectrometry.
resultsThere was no association between serum total 25(OH)D and serum LDL-C. However, circulating 3-epi-25(OH)D3 was negatively related to serum LDL-C (r = -0.077, P <0.05), while no such association was found for non-epimeric 25(OH)D3 (r =0.030, P = 0.33). On the other hand, both 3-epi-25(OH)D3 (r = 0.175, P <0.001) and non-epimeric 25(OH)D3 (r = 0.142, P <0.001) were positively related to serum triglyceride (TRIG) levels. In multiple linear regression models with age, gender, body mass index , urban residence, education, hypertension and education as covariates, it was found that 3-epi-25(OH)D3 was independently associated with serum LDL-C (beta = -0.12, P <0.01), while non-epimeric 25(OH)D3 was positively related to LDL-C (beta = 0.13, P = 0.002). For TRIG, there were positive association with 3-epi-25(OH)D3 (beta = 0.27, P <0.001) and negative association with non-epimeric 25(OH)D3 (beta = - 0.10, P = 0.011) independent of age, gender, urban resident and education.
conclusionsThere is a discrepant association of 25(OH)D levels with serum lipids according to 25(OH)D epimeric forms.
