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

objectiveThe objective of this study was to systematically review all the published articles examining the effects of low serum vitamin D concentration and vitamin D supplementation on muscle, balance and gait performance among people aged 65 and older.

methodsAn English and French Medline search ranging from January 2004 to November 2008 indexed under the Medical Subject Heading (MeSH) terms "aged OR aged, 80 and over" AND "Vitamin D OR Vitamin D Deficiency" combined with the terms "Gait" OR "Gait Apraxia" OR "Gait Disorders, Neurologic" OR "Walking" OR "Mobility Limitation" OR "Polyneuropathy" OR "Proprioception" OR "Ataxia" OR "Accidental Falls" was performed.

resultsOf the 102 selected studies, 16 met the selection criteria and were included in the final analysis. There were 8 observational studies and 8 interventional studies. The number of participants ranged from 24 to 33067. A majority of studies examined community-dwelling older women. Five observational studies showed a significant positive association, whereas three studies did not. Four of the 5 studies and two of the 3 studies which tested the vitamin D supplementation effect, respectively on balance and gait, showed no significant effect. Four studies showed a significant effect on muscle strength, while this effect was not observed in three others studies. In addition, there was no significant association between vitamin D supplementation and an improvement of the sit-to-stand test results in 50% of the studies.

conclusionsThe findings show that the association between vitamin D and physical performance remains controversial. Observational studies and clinical trials yielded divergent results, which highlights the complex and to date still poorly understood association between serum vitamin D concentration or vitamin D supplementation and physical performance.
