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

objectiveIn the present study, we aimed to investigate the relationship between serum vitamin D3 concentration and anaemia in patients with chronic kidney disease (CKD) in China, to assist understanding of the effects of vitamin D treatment in such patients.

methodsA total of 225 patients with CKD were enrolled and a range of laboratory parameters were measured. The participants were allocated to three groups, according to their serum 25-hydroxyvitamin D3 concentration: a severe deficiency group, a deficiency group, and a sufficiency group. The prevalences of anaemia in the three groups were assessed, and the factors associated with anaemia in patients with CKD were analysed using logistic regression.

resultsThe prevalences of anaemia were 79.5% in the severe deficiency group, 63.5% in the deficiency group, and 48.0% in the sufficiency group. The prevalence of anaemia gradually increased with the severity of vitamin D3 deficiency. The prevalences of anaemia in participants with stages 1 to 5 CKD were 21.1%, 30.4%, 39.5%, 78.7%, and 94.6%, respectively.

conclusionVitamin D3 deficiency may increase the risk of anaemia in patients with CKD.
