1 · What the graph read from it

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.

2 · The registry

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

Mixed findings regarding effects of vitamin E on bone metabolism existed. We were the first to find a negative association between serum α-tocopherol concentration and bone mineral density in the US elderly population. Using vitamin E supplement as α-tocopherol to promote bone health was not warranted at this time.

introductionThe aim of the study is to examine the associations between serum vitamin E (α-tocopherol and γ-tocopherol) status and bone mineral density (BMD) among the US elderly population.

methodsWe used data from the National Health and Nutrition Examination Survey (NHANES) 2005-2006. This cross-sectional study finally included 989 subjects who were not having liver diseases, kidney diseases, rheumatoid arthritis, or cancers; were not treated for osteoporosis; and were not taking steroids or female hormones. Multivariable linear regression models were employed to examine the associations between serum vitamin E (α-tocopherol and γ-tocopherol) concentration and BMDs of total spine and femoral neck after adjusting for covariates and potential confounders.

resultsSignificant differences in serum α-tocopherol and γ-tocopherol levels, dietary intake of vitamin E as α-tocopherol, and BMDs of total spine and femoral neck were presented between male and female participants. Serum α-tocopherol and γ-tocopherol concentrations were found to be inversely correlated (r = -0.169, P < 0.001). In univariable linear models, significant negative associations between serum α-tocopherol and both total spine BMD (β = -0.0014, P = 0.002) and femoral neck BMD (β = -0.0017, P < 0.001) were found. Accounting for covariates, serum α-tocopherol level was negatively associated with femoral neck BMD (β = -0.0007, P = 0.028).

conclusionsThis study found a negative association between serum α-tocopherol concentration and femoral neck BMD in the US elderly population, suggesting a harmful effect of α-tocopherol on bone health. Future studies are warranted to further examine the dose-response relationships between individual vitamin E isomers and bone metabolism.
