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

aims/hypothesisVitamin D deficiency is common in people with type 1 diabetes, but its role in disease progression is unclear. Our aim was to assess the prevalence of vitamin D deficiency in prediabetes (defined as the presence of multiple islet autoantibodies), and investigate whether or not progression to type 1 diabetes is faster in children with vitamin D deficiency and multiple islet autoantibodies.

methodsLevels of 25-hydroxyvitamin D [25(OH)D] were measured in 108 children with multiple islet autoantibodies within 2 years of islet autoantibody seroconversion, in 406 children who remained islet autoantibody-negative and in 244 patients with newly diagnosed type 1 diabetes. Children with multiple islet autoantibodies were prospectively followed for a median of 5.8 years (interquartile range 3.4-8.6 years) to monitor progression to type 1 diabetes.

resultsIn the cross-sectional analysis, 25(OH)D levels were lower and the prevalence of vitamin D deficiency (<50 nmol/l) was higher in children with prevalent multiple islet autoantibodies than in islet autoantibody-negative children (59.9 ± 3.0 vs 71.9 ± 1.5 nmol/l; p < 0.001; 39.8% vs 28.3%; p = 0.021). The differences in vitamin D levels between the groups were greatest in summer. The cumulative incidence of type 1 diabetes at 10 years after seroconversion was similar between children with vitamin D deficiency and those with sufficient vitamin D levels (51.8% [95% CI 29.3, 74.3] vs 55.4% [95% CI 35.5, 72.3], p = 0.8). CONCLUSIONS/

interpretationVitamin D levels were lower in children with multiple islet autoantibodies and in children with type 1 diabetes than in autoantibody-negative children. However, vitamin D deficiency was not associated with faster progression to type 1 diabetes in children with multiple islet autoantibodies.
