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

Polymorphisms in the vitamin D receptor (VDR) gene are some of the most studied in relation to skeletal muscle traits and significant associations have been observed by multiple groups. One such paper by our group provided the first evidence of a genetic association with sarcopenia in men, but that finding has yet to be replicated in an independent cohort. In the present study, we examined multiple VDR polymorphisms in relation to skeletal muscle traits and sarcopenia in 864 men and women across the adult age span. In addition to VDR genotypes and haplotypes, measurements of skeletal muscle strength and fat-free mass (FFM) were determined in all subjects and a measure of sarcopenia was calculated. We observed significant associations between Fok1 and Bsm1 genotypes and skeletal muscle strength in men and women, though these associations were modest and no significant associations were observed for these polymorphisms and muscle mass traits nor for Bsm1-Taq1 haplotype with muscle strength. Fok1 FF genotype was associated with an increased the risk of sarcopenia in older women compared to f-allele carriers (1.3-fold higher risk). These results support previous findings that VDR genetic variation appears to impact skeletal muscle strength and risk for sarcopenia but the influence is modest.
