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

introductionThe effect of vitamin D on maintaining bone health is well researched and its role in the various metabolic stages of fracture healing has become evident, the clinical effects of a vitamin D deficiency in human fracture healing are less well described. Considering today's high prevalence of vitamin D deficiency, the aim of this present study was to investigate the effect of vitamin D status on human adult fracture healing.

methodsThe serum calcidiol concentration was measured in a cohort of adult patients with a fracture in the upper or lower extremity between September 2012 and October 2013. Deficient patients (serum calcidiol <50 nmol/L) were treated with vitamin D. Clinical and radiological consolidation was determined.

resultsVitamin D concentration was measured in 617 patients; 249 (40%) were vitamin D deficient, they subsequently received vitamin D supplements. In 141 patients with a deficiency vitamin D was measured again after 4 months; 111 patients (78.7%) were no longer vitamin D deficient, and 30 remained vitamin D deficient. In six patients of the entire cohort, a clinical delayed union was described. The incidence of delayed union was higher in the group that remained vitamin D deficient (9.7%) compared to the patients who were not initially deficient (0.3%) and those who were no longer deficient after supplementation (1.7%;

conclusionThe results of this research suggest that the vitamin D status at time of fracture affects fracture healing. Further research is needed to confirm these results.
