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

backgroundDespite the certain role of both vitamin D and adiponectin in the regulation of insulin sensitivity, the interaction between these two agents has remained uncertain.

objectiveThe present study aimed to determine whether vitamin D is able to change plasma adiponectin and affect glucose homeostasis and insulin sensitivity in first-degree relatives of subjects with type 2 diabetes.

methodsThis randomized clinical trial was conducted at Clinic of Shahid Sadoughi Hospital in Yazd, Iran, from January 25, 2012 to December 25, 2014. In this randomized, double-blinded controlled trial, 64 first-degree relatives of type 2 diabetic patients were assigned randomly to receive either vitamin D supplement (50000 IU vitamin D tablet weekly) plus lifestyle change as the intervention group (n = 32) or placebo plus lifestyle change as the control group (n = 32) for twelve weeks (three months).

resultsFifty-three patients (28 in the intervention group and 25 in the control group) completed the study. Serum levels of vitamin D increased while insulin level and consequently insulin resistance (calculated by HOMA formula) significantly decreased in the case group (p-value <0.001 for all variables). Although the values of these three biomarkers showed a slight increase in control group, the changes were not statistically significant. The levels of the changes in other markers including adiponectin, Fasting Blood Sugar (FBS), triglyceride, and total cholesterol remained insignificant in both study groups after completing interventions compared with before interventions.

conclusionThis study showed that decreased insulin resistance is expected by administrating vitamin D supplement in first-degree relatives of the patients with diabetes mellitus.

trial registrationThe trial was registered at the Iranian Registry of Clinical Trials (http://www.irct.ir) with the IRCT ID: 201105176430N1.
